Add a HID_QUIRK_NO_INIT_REPORTS quirk for the Dell K12A keyboard-dock,
which can be used with various Dell Venue 11 models.

Without this quirk the keyboard/touchpad combo works fine when connected
at boot, but when hotplugged 9 out of 10 times it will not work properly.
Adding the quirk fixes this.

The state of the center button was not reported to userspace for the
2nd-gen Intuos Pro S when used over Bluetooth due to the pad handling
code not being updated to support its reduced number of buttons. This
patch uses the actual number of buttons present on the tablet to
assemble a button state bitmap.

The syzbot fuzzer discovered a bad race between in the usbhid driver
between usbhid_stop() and usbhid_close().  In particular,
usbhid_stop() does:

	usb_free_urb(usbhid->urbin);
	...
	usbhid->urbin = NULL; /* don't mess up next start */

and usbhid_close() does:

	usb_kill_urb(usbhid->urbin);

with no mutual exclusion.  If the two routines happen to run
concurrently so that usb_kill_urb() is called in between the
usb_free_urb() and the NULL assignment, it will access the
deallocated urb structure -- a use-after-free bug.

This patch adds a mutex to the usbhid private structure and uses it to
enforce mutual exclusion of the usbhid_start(), usbhid_stop(),
usbhid_open() and usbhid_close() callbacks.

This reverts commit 15893fa4.

The referenced commit broke pen and touch input for a variety of devices
such as the Cintiq Pro 32. Affected devices may appear to work normally
for a short amount of time, but eventually loose track of actual touch
state and can leave touch arbitration enabled which prevents the pen
from working. The commit is not itself required for any currently-available
Bluetooth device, and so we revert it to correct the behavior of broken
devices.

This breakage occurs due to a mismatch between the order of collections
and the order of usages on some devices. This commit tries to read the
contact count before processing events, but will fail if the contact
count does not occur prior to the first logical finger collection. This
is the case for devices like the Cintiq Pro 32 which place the contact
count at the very end of the report.

Without the contact count set, touches will only be partially processed.
The `wacom_wac_finger_slot` function will not open any slots since the
number of contacts seen is greater than the expectation of 0, but we will
still end up calling `input_mt_sync_frame` for each finger anyway. This
can cause problems for userspace separate from the issue currently taking
place in the kernel. Only once all of the individual finger collections
have been processed do we finally get to the enclosing collection which
contains the contact count. The value ends up being used for the *next*
report, however.

This delayed use of the contact count can cause the driver to loose track
of the actual touch state and believe that there are contacts down when
there aren't. This leaves touch arbitration enabled and prevents the pen
from working. It can also cause userspace to incorrectly treat single-
finger input as gestures.

We've recently switched from extracting the value of HID_DG_CONTACTMAX
at a fixed offset (which may not be correct for all tablets) to
injecting the report into the driver for the generic codepath to handle.
Unfortunately, this change was made for *all* tablets, even those which
aren't generic. Because `wacom_wac_report` ignores reports from non-
generic devices, the contact count never gets initialized. Ultimately
this results in the touch device itself failing to probe, and thus the
loss of touch input.

This commit adds back the fixed-offset extraction for non-generic devices.

This is partly for readability - using named arguments instead of
numbered ones makes it muchmore obvious just what is going on.  Using
"%[efault]" instead of "%4" for the special -EFAULT constant just means
that you don't have to count the arguments to see what's up.

But the motivation for all this cleanup is that when we'll start to
conditionally use "asm goto" even for the __get_user_asm() case, the
argument numbers will depend on whether we have an error output, or an
error label we can just directly jump to.

So this moves us towards named arguments for the same reason that we
have to use named arguments for the asms that use SET_CC(): numbering
will eventually become similarly unreliable and depends on whether we
can use particular compiler features or not.

This is the exact same thing as 36807856 ("x86: get rid of 'rtype'
argument to __put_user_goto() macro") except it's about __get_user_asm()
rather than __put_user_goto().

The reasons are the same: having the low-level asm access the argument
with a different size than the compiler thinks it does is fundamentally
wrong.

But unlike the __put_user_goto() case, we actually did tell the compiler
that we used a bigger variable (either long or long long), and then only
filled in the low bits, and ended up "fixing" this by casting the result
to the proper pointer type.

That's because we needed to use a non-qualified type (the user pointer
might be a const pointer!), and that makes this a bit more painful.  Our
'__inttype()' macro used to be lazy and only differentiate between "fits
in a register" or "needs two registers".

So this fix had to also make that '__inttype()' macro more precise.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

The 'rtype' argument goes back to pre-git (and pre-BK) times, and comes
from the fact that we used to not necessarily have the same type sizes
for the arguments of the inline asm as we did for the actual accesses we
did.

So 'rtype' is the 'register type' - the override of the register size in
the inline asm when it doesn't match the actual size of the variable we
use as the output argument (for when you used "put_user()" on an "int"
value that was assigned to a byte-sized user space access etc).

That mismatch doesn't actually exist any more, and should probably never
have existed in the first place.  It's a horrid bug just waiting to
happen (using more - or less - of the variable that the compiler
expected us to use).

I think we had some odd casting going on to hide the effects of that
oddity after-the-fact, but those are long gone, and these days we should
always have the right size value in the first place, using things like

        __typeof__(*(ptr)) __pu_val = (x);

and gcc should thus have the right register size without any manual
'rtype' games.

Pull Kbuild updates from Masahiro Yamada:
 "Build system:

   - add CONFIG_UNUSED_KSYMS_WHITELIST, which will be useful to define a
     fixed set of export symbols for Generic Kernel Image (GKI)

   - allow to run 'make dt_binding_check' without .config

   - use full schema for checking DT examples in *.yaml files

   - make modpost fail for missing MODULE_IMPORT_NS(), which makes more
     sense because we know the produced modules are never loadable

   - Remove unused 'AS' variable

  Kconfig:

   - sanitize DEFCONFIG_LIST, and remove ARCH_DEFCONFIG from Kconfig
     files

   - relax the 'imply' behavior so that symbols implied by 'y' can
     become 'm'

   - make 'imply' obey 'depends on' in order to make 'imply' really weak

  Misc:

   - add documentation on building the kernel with Clang/LLVM

   - revive __HAVE_ARCH_STRLEN for 32bit sparc to use optimized strlen()

   - fix warning from deb-pkg builds when CONFIG_DEBUG_INFO=n

Pull SELinux updates from Paul Moore:
 "We've got twenty SELinux patches for the v5.7 merge window, the
  highlights are below:

   - Deprecate setting /sys/fs/selinux/checkreqprot to 1.

     This flag was originally created to deal with legacy userspace and
     the READ_IMPLIES_EXEC personality flag. We changed the default from
     1 to 0 back in Linux v4.4 and now we are taking the next step of
     deprecating it, at some point in the future we will take the final
     step of rejecting 1.

   - Allow kernfs symlinks to inherit the SELinux label of the parent
     directory. In order to preserve backwards compatibility this is
     protected by the genfs_seclabel_symlinks SELinux policy capability.

   - Optimize how we store filename transitions in the kernel, resulting
     in some significant improvements to policy load times.

   - Do a better job calculating our internal hash table sizes which
     resulted in additional policy load improvements and likely general
     SELinux performance improvements as well.

   - Remove the unused initial SIDs (labels) and improve how we handle
     initial SIDs.

   - Enable per-file labeling for the bpf filesystem.

   - Ensure that we properly label NFS v4.2 filesystems to avoid a
     temporary unlabeled condition.

   - Add some missing XFS quota command types to the SELinux quota
     access controls.

   - Fix a problem where we were not updating the seq_file position
     index correctly in selinuxfs.

   - We consolidate some duplicated code into helper functions.

   - A number of list to array conversions.

   - Update Stephen Smalley's email address in MAINTAINERS"

Pull audit updates from Paul Moore:
 "We've got two audit patches for the v5.7 merge window with a stellar
  14 lines changed between the two patches. The patch descriptions are
  far more lengthy than the patches themselves, which is a very good
  thing for patches this size IMHO. The patches pass our test suites and
  a quick summary is below:

   - Stop logging inode information when updating an audit file watch.

     Since we are not changing the inode, or the fact that we are
     watching the associated file, the inode information is just noise
     that we can do without.

   - Fix a problem where mandatory audit records were missing their
     accompanying audit records (e.g. SYSCALL records were missing).

     The missing records often meant that we didn't have the necessary
     context to understand what was going on when the event occurred"

Pull gfs2 updates from Bob Peterson:
 "We've got a lot of patches (39) for this merge window. Most of these
  patches are related to corruption that occurs when journals are
  replayed. For example:

   1. A node fails while writing to the file system.
   2. Other nodes use the metadata that was once used by the failed
      node.
   3. When the node returns to the cluster, its journal is replayed, but
      the older metadata blocks overwrite the changes from step 2.

  Summary:

   - Fixed the recovery sequence to prevent corruption during journal
     replay.

   - Many bug fixes found during recovery testing.

   - New improved file system withdraw sequence.

   - Fixed how resource group buffers are managed.

   - Fixed how metadata revokes are tracked and written.

   - Improve processing of IO errors hit by daemons like logd and
     quotad.

   - Improved error checking in metadata writes.

Pull btrfs updates from David Sterba:
 "A number of core changes that make things work better in general, code
  is simpler and cleaner.

  Core changes:

   - per-inode file extent tree, for in memory tracking of contiguous
     extent ranges to make sure i_size adjustments are accurate

   - tree root structures are protected by reference counts, replacing
     SRCU that did not cover some cases

   - leak detector for tree root structures

   - per-transaction pinned extent tracking

   - buffer heads are replaced by bios for super block access

   - speedup of extent back reference resolution, on an example test
     scenario the runtime of send went down from a hour to minutes

   - factor out locking scheme used for subvolume writer and NOCOW
     exclusion, abstracted as DREW lock, double reader-writer exclusion
     (allow either readers or writers)

   - cleanup and abstract extent allocation policies, preparation for
     zoned device support

   - make reflink/clone_range work on inline extents

   - add more cancellation point for relocation, improves long response
     from 'balance cancel'

   - add page migration callback for data pages

   - switch to guid for uuids, with additional cleanups of the interface

   - make ranged full fsyncs more efficient

   - removal of obsolete ioctl flag BTRFS_SUBVOL_CREATE_ASYNC

   - remove b-tree readahead from delayed refs paths, avoiding seek and
     read unnecessary blocks

  Features:

   - v2 of ioctl to delete subvolumes, allowing to delete by id and more
     future extensions

  Fixes:

   - fix qgroup rescan worker that could block umount

   - fix crash during unmount due to race with delayed inode workers

   - fix dellaloc flushing logic that could create unnecessary chunks
     under heavy load

   - fix missing file extent item for hole after ranged fsync

   - several fixes in relocation error handling

  Other:

   - more documentation of relocation, device replace, space
     reservations

   - many random cleanups"
