2021-06-02mfd: rn5t618: Fix IRQ trigger by changing it to level modeAndreas Kemnade1-1/+1
During more massive generation of interrupts, the IRQ got stuck, and the subdevices did not see any new interrupts. That happens especially at wonky USB supply in combination with ADC reads.

2021-06-02mfd: syscon: Free the allocated name field of struct regmap_configLimeng1-1/+1
The commit 529a1101212a("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 94cc89eb8fa5("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 ...

2021-06-02mfd: mt6397: Use named IRQs instead of index (keys)Mattijs Korpershoek1-4/+4
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.

2021-05-08drm/i915/display: fix compiler warning about array overrunLinus Torvalds1-1/+12
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. There may be some underlying bug in here that caused this confusion, but this is at least no worse than the existing situation that could use random data off the stack.
