The commit 529a1101("mfd: syscon: Don't free allocated name for regmap_config") doesn't free the allocated name field of struct regmap_config, but introduce a memory leak. There is another commit 94cc89eb("regmap: debugfs: Fix handling of name string for debugfs init delays") fixing this debugfs init issue from root cause. With this fixing, the name field in struct regmap_debugfs_node is removed. When initialize debugfs for syscon driver, the name field of struct regmap_config is not used anymore. So, the allocated name field of struct regmap_config is need to be freed directly after regmap initialization to avoid memory leak.

Currently the software node is removed in error case and at ->remove() stage unconditionally, that ruins the symmetry. Besides, in some cases, when mfd_add_device() fails, the device_remove_software_node() call may lead to NULL pointer dereference: BUG: kernel NULL pointer dereference, address: 00000000 ... EIP: strlen+0x12/0x20 ... kernfs_name_hash+0x13/0x70 kernfs_find_ns+0x32/0xc0 kernfs_remove_by_name_ns+0x2a/0x90 sysfs_remove_link+0x16/0x30 software_node_notify.cold+0x34/0x6b device_remove_software_node+0x5a/0x90 mfd_add_device.cold+0x30a/0x427 Fix all these by guarding device_remove_software_node() with a conditional and locating it at the right place.

Currently only two interrupts supported is added in wcd934x interrupt controller, however if we are adding more interrupts the file will become too much unreadable. So add a macro to make adding new interrupts easy and also convert existing slim and soundwire interrupts to use it. This is in preparation to enable Multi Button Headset Control support on this codec. WCD934x supports Multi Button Headset control which enable headset detection along with headset button detection. This patch adds interrupts required for MBHC functionality. Signed-off-by:

Add compatible strings and interrupts for pmic keys which serves as child device of MFD. MT6358 has two interrupts per key: one for press, another one for release (_R) Signed-off-by:

Mattijs Korpershoek authored
Some pmics of the mt6397 family (such as MT6358), have two IRQs per physical key: one for press event, another for release event. The mtk-pmic-keys driver assumes that each key only has one IRQ. The key index and the RES_IRQ resource index have a 1/1 mapping. This won't work for MT6358, as we have multiple resources (2) for one key. To prepare mtk-pmic-keys to support MT6358, retrieve IRQs by name instead of by index. Note: The keys_resources are not part of the device-tree bindings so this won't break any DT schemas.

Commit b9d79e4c ("fbmem: Mark proc_fb_seq_ops as __maybe_unused") places the '__maybe_unused' in an entirely incorrect location between the "struct" keyword and the structure name. It's a wonder that gcc accepts that silently, but clang quite reasonably warns about it: drivers/video/fbdev/core/fbmem.c:736:21: warning: attribute declaration must precede definition [-Wignored-attributes] static const struct __maybe_unused seq_operations proc_fb_seq_ops = { ^ Fix it.

Pull scheduler fixes from Thomas Gleixner: "A set of scheduler updates: - Prevent PSI state corruption when schedule() races with cgroup move. A recent commit combined two PSI callbacks to reduce the number of cgroup tree updates, but missed that schedule() can drop rq::lock for load balancing, which opens the race window for cgroup_move_task() which then observes half updated state. The fix is to solely use task::ps_flags instead of looking at the potentially mismatching scheduler state - Prevent an out-of-bounds access in uclamp caused bu a rounding division which can lead to an off-by-one error exceeding the buckets array size. - Prevent unfairness caused by missing load decay when a task is attached to a cfs runqueue. The old load of the task was attached to the runqueue and never removed. Fix it by enforcing the load update through the hierarchy for unthrottled run queue instances. - A documentation fix fot the 'sched_verbose' command line option" * tag 'sched-urgent-2021-05-09' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: sched/fair: Fix unfairness caused by missing load decay sched: Fix out-of-bound access in uclamp psi: Fix psi state corruption when schedule() races with cgroup move sched,doc: sched_debug_verbose cmdline should be sched_verbose -

intel_dp_check_mst_status() uses a 14-byte array to read the DPRX Event Status Indicator data, but then passes that buffer at offset 10 off as an argument to drm_dp_channel_eq_ok(). End result: there are only 4 bytes remaining of the buffer, yet drm_dp_channel_eq_ok() wants a 6-byte buffer. gcc-11 correctly warns about this case: drivers/gpu/drm/i915/display/intel_dp.c: In function ‘intel_dp_check_mst_status’: drivers/gpu/drm/i915/display/intel_dp.c:3491:22: warning: ‘drm_dp_channel_eq_ok’ reading 6 bytes from a region of size 4 [-Wstringop-overread] 3491 | !drm_dp_channel_eq_ok(&esi[10], intel_dp->lane_count)) { | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/i915/display/intel_dp.c:3491:22: note: referencing argument 1 of type ‘const u8 *’ {aka ‘const unsigned char *’} In file included from drivers/gpu/drm/i915/display/intel_dp.c:38: include/drm/drm_dp_helper.h:1466:6: note: in a call to function ‘drm_dp_channel_eq_ok’ 1466 | bool drm_dp_channel_eq_ok(const u8 link_status[DP_LINK_STATUS_SIZE], | ^~~~~~~~~~~~~~~~~~~~ 6:14 elapsed This commit just extends the original array by 2 zero-initialized bytes, avoiding the warning.
