2024-09-20Input: adp5588-keys - fix check on return codeNuno Sa
During adp5588_setup(), we read all the events to clear the event FIFO. However, adp5588_read() just calls i2c_smbus_read_byte_data() which returns the byte read in case everything goes well. Hence, we need to explicitly check for a negative error code instead of checking for something different than 0.

2024-09-13Input: i8042 - add TUXEDO Stellaris 15 Slim Gen6 AMD to i8042 quirk tableWerner Sembach
The Gen6 devices have the same problem and the same Solution as the Gen5 ones. Some TongFang barebones have touchpad and/or keyboard issues after suspend, fixable with nomux + reset + noloop + nopnp. Luckily, none of them have an external PS/2 port so this can safely be set for all of them. I'm not entirely sure if every device listed really needs all four quirks, but after testing and production use, no negative effects could be observed when setting all four.

2024-09-13Input: tegra-kbc - use of_property_read_variable_u32_array() and ↵Rob Herring (Arm)
of_property_present() There's no need to get the length of an DT array property before parsing the array. of_property_read_variable_u32_array() takes a minimum and maximum length and returns the actual length (or error code). This is part of a larger effort to remove callers of of_get_property() and similar functions. of_get_property() leaks the DT property data pointer which is a problem for dynamically allocated nodes which may be freed.

2024-09-05Input: zforce_ts - stop treating VDD regulator as optionalDmitry Torokhov
This regulator is not optional from the controller point of view, so stop treating it as such. For hard-wired designs that omit the regulator from their device trees regulator subsystem will create a dummy instance. This may introduce unnecessary delay of 100us in case of dummy regulator, but if it is important the driver should be marked as using asynchronous probing to avoid even longer delays waiting for the command completions. Also use usleep_range() instead of udelay() to avoid spinning.

2024-09-05Input: zforce_ts - make parsing of contacts less confusingDmitry Torokhov
Zforce touch data packet consists of a byte representing number of contacts followed by several chunks with length of 9 bytes representing each contact. Instead of accounting for the leading byte by increasing offset of each field in contacts by one introduce a pointer to contact data and point it appropriately. This avoids awkward constructs like: point.prblty = payload[9 * i + 9]; which makes it seem like there is off-by-one error, in favor of more straightforward: point.prblty = p[8]; Tested-by: Andreas Kemnade <andreas@kemnade.info> # Tolino Shine2HD Link: https://lore.kernel.org/r/20240824055047.1706392-11-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

There is a small chance that ts->suspending flag may change while the interrupt handler is running.

2024-08-31bcachefs: Revert lockless buffered IO pathKent Overstreet
We had a report of data corruption on nixos when building installer images. https://github.com/NixOS/nixpkgs/pull/321055#issuecomment-2184131334 It seems that writes are being dropped, but only when issued by QEMU, and possibly only in snapshot mode. It's undetermined if it's write calls are being dropped or dirty folios. Further testing, via minimizing the original patch to just the change that skips the inode lock on non appends/truncates, reveals that it really is just not taking the inode lock that causes the corruption: it has nothing to do with the other logic changes for preserving write atomicity in corner cases. It's also kernel config dependent: it doesn't reproduce with the minimal kernel config that ktest uses, but it does reproduce with nixos's distro config. Bisection the kernel config initially pointer the finger at page migration or compaction, but it appears that was erroneous; we haven't yet determined what kernel config option actually triggers it. Sadly it appears this will have to be reverted since we're getting too close to release and my plate is full, but we'd _really_ like to fully debug it. My suspicion is that this patch is exposing a preexisting bug - the inode lock actually covers very little in IO paths, and we have a different lock (the pagecache add lock) that guards against races with truncate here.

2024-08-31Input: snvs_pwrkey - use devm_clk_get_optional_enabled()Dmitry Torokhov
Switch to using devm_clk_get_optional_enabled() helper instead of acquiring the clock with devm_clk_get_optional(), enabling it, and defining and installing a custom devm action to call clk_disable().

These are fixes for regressions that Guenther has been reporting, and the maintainers haven't picked up and sent in. With rc6 fairly imminent, I'm taking them directly from Guenter. * 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging: apparmor: fix policy_unpack_test on big endian systems Revert "MIPS: csrc-r4k: Apply verification clocksource flags" microblaze: don't treat zero reserved memory regions as error
