The i2c-hid driver would quietly fail to probe the i2c-hid sensor-hub
with an ACPI device-id of SMO91D0 every other boot.

Specifically, the i2c_smbus_read_byte() "Make sure there is something at
this address" check would fail every other boot.

It seems that the BIOS does not properly reset/power-cycle the device
leaving it in a confused state where it refuses to respond to i2c-xfers.
On boots where probing the device failed, the driver-core puts the device
in D3 after the probe-failure, which causes the probe to succeed the next
boot.

Putting the device in D3 from the shutdown-handler fixes the sensors not
working every other boot.

This has been tested on both a Lenovo Miix 2-10 and a Dell Venue 8 Pro 5830
both of which use an i2c-hid sensor-hub with an ACPI id of SMO91D0.

Note that it is safe to call acpi_device_set_power() with a NULL pointer
as first argument, so on none ACPI enumerated devices this change is a
no-op.

The Varmilo VA104M Keyboard (04b4:07b1, reported as Varmilo Z104M)
exposes media control hotkeys as a USB HID consumer control device, but
these keys do not work in the current (5.8-rc1) kernel due to the
incorrect HID report descriptor. Fix the problem by modifying the
internal HID report descriptor.

More specifically, the keyboard report descriptor specifies the
logical boundary as 572~10754 (0x023c ~ 0x2a02) while the usage
boundary is specified as 0~10754 (0x00 ~ 0x2a02). This results in an
incorrect interpretation of input reports, causing inputs to be ignored.
By setting the Logical Minimum to zero, we align the logical boundary
with the Usage ID boundary.

Some notes:

* There seem to be multiple variants of the VA104M keyboard. This
  patch specifically targets 04b4:07b1 variant.

* The device works out-of-the-box on Windows platform with the generic
  consumer control device driver (hidserv.inf). This suggests that
  Windows either ignores the Logical Minimum/Logical Maximum or
  interprets the Usage ID assignment differently from the linux
  implementation; Maybe there are other devices out there that only
  works on Windows due to this problem?

The usb-hid keyboard-dock for the Acer Switch 10 SW5-012 model declares
an application and hid-usage page of 0x0088 for the INPUT(4) report which
it sends. This reports contains 2 8-bit fields which are declared as
HID_MAIN_ITEM_VARIABLE.

The keyboard-touchpad combo never actually generates this report, except
when the touchpad is toggled on/off with the Fn + F7 hotkey combo. The
toggle on/off is handled inside the keyboard-dock, when the touchpad is
toggled off it simply stops sending events.

When the touchpad is toggled on/off an INPUT(4) report is generated with
the first content byte set to 120/121, before this commit the kernel
would report this as ABS_MISC 120/121 events.

Patch the descriptor to replace the HID_MAIN_ITEM_VARIABLE with
HID_MAIN_ITEM_RELATIVE (because no key-presss release events are send)
and add mappings for the 0x00880078 and 0x00880079 usages to generate
touchpad on/off key events when the touchpad is toggled on/off.

- i2c-hid support for wakeup from suspend-to-idle

Many laptops can be woken up from Suspend-to-Idle by touchpad. This is
also the default behavior on other OSes.

However, if touchpad and touchscreen contact to each other when lid is
closed, wakeup events can be triggered inadventertly.

So let's disable the wakeup by default, but enable the wakeup capability
so users can enable it at their own discretion.

 "Here are some SPDX-specific changes for 5.10-rc1.

  They include:

   - driver fixes to make spdxcheck.pl work properly

   - add GFDL licenses as "deprecated" but required due to some of our
     documentation using them

   - add Zlib license as "deprecated" but required because we have code
     with this license in the tree.

   - convert some drivers to have SPDX identifiers that previously
     didn't have them.

A recent change to the checksum code removed usage of some extra
arguments, alongside with storage on the stack for those, and the stack
pointer no longer needed to be adjusted in the function prologue.

But a left over subtraction wasn't removed in the function epilogue,
causing the function to return with the stack pointer moved 16 bytes
away from where it should have.  This corrupted local state and lead to
weird crashes.

This simply removes the leftover instruction from the epilogue.

   instead have block core make direct call to blk_mq_submit_bio().

 - Update DM cryot to not use drivers that set
   CRYPTO_ALG_ALLOCATES_MEMORY.
