2021-06-05Input: resistive-adc-touch - fix uninitialized variable 'press'Colin Ian King
In the case where st->ch_map[GRTS_CH_PRESSURE] < GRTS_MAX_CHANNELS is false and also st->ch_map[GRTS_CH_Z1] < GRTS_MAX_CHANNELS is false the variable press is not initialized and contains garbage. In this situation st->pressure is also false, so we do not actually use press value, but it is impossible for the compiler to realize this, and it emits "uninitialized variable" warning. Fix this by initializing press to 0 and allows us to also remove an else clause that sets press to 0.

On Qualcomm Technologies, Inc. PMIC PMK8350, the PON peripheral is split into two peripherals: PON_HLOS and PON_PBS. The application processor only has write access to PON_HLOS which limits it to only receiving PON interrupts. Add support for the PMK8350 PON_HLOS peripheral so that its KPDPWR_N and RESIN_N interrupts can be used to detect key presses.

2021-06-01Input: edt-ft5x06 - add support for iovcc-supplyStephan Gerhold
At the moment, the edt-ft5x06 driver can control a single regulator ("vcc"). However, some FocalTech touch controllers have an additional IOVCC pin that should be supplied with the digital I/O voltage. The I/O voltage might be provided by another regulator that should also be kept on. Otherwise, the touchscreen can randomly stop functioning if the regulator is turned off because no other components still require it. Implement (optional) support for also enabling an "iovcc-supply". The datasheet specifies a delay of ~ 10us before enabling VDD/VCC after IOVCC is enabled, so make sure to enable IOVCC first.

2021-04-23mm/filemap: fix mapping_seek_hole_data on THP & 32-bitHugh Dickins
No problem on 64-bit, or without huge pages, but xfstests generic/285 and other SEEK_HOLE/SEEK_DATA tests have regressed on huge tmpfs, and on 32-bit architectures, with the new mapping_seek_hole_data(). Several different bugs turned out to need fixing. u64 cast to stop losing bits when converting unsigned long to loff_t (and let's use shifts throughout, rather than mixed with * and /). Use round_up() when advancing pos, to stop assuming that pos was already THP-aligned when advancing it by THP-size. (This use of round_up() assumes that any THP has THP-aligned index: true at present and true going forward, but could be recoded to avoid the assumption.) Use xas_set() when iterating away from a THP, so that xa_index stays in synch with start, instead of drifting away to return bogus offset. Check start against end to avoid wrapping 32-bit xa_index to 0 (and to handle these additional cases, seek_data or not, it's easier to break the loop than goto: so rearrange exit from the function).

Command 'perf ftrace -v -- ls' fails in s390 (at least 5.12.0rc6). The root cause is a missing pointer dereference which causes an array element address to be used as PID. Fix this by extracting the PID.

2021-04-23perf auxtrace: Fix potential NULL pointer dereferenceLeo Yan
In the function auxtrace_parse_snapshot_options(), the callback pointer "itr->parse_snapshot_options" can be NULL if it has not been set during the AUX record initialization. This can cause tool crashing if the callback pointer "itr->parse_snapshot_options" is dereferenced without performing NULL check. Add a NULL check for the pointer "itr->parse_snapshot_options" before invoke the callback.
