2025-03-09Input: iqs7222 - preserve system status registerJeff LaBundy
Some register groups reserve a byte at the end of their continuous address space. Depending on the variant of silicon, this field may share the same memory space as the lower byte of the system status register (0x10). In these cases, caching the reserved byte and writing it later may effectively reset the device depending on what happened in between the read and write operations. Solve this problem by avoiding any access to this last byte within offending register groups. This method replaces a workaround which attempted to write the reserved byte with up-to-date contents, but left a small window in which updates by the device could have been clobbered. Now that the driver does not touch these reserved bytes, the order in which the device's registers are written no longer matters, and they can be written in their natural order. The new method is also much more generic, and can be more easily extended to new variants of silicon with different register maps. As part of this change, the register read and write functions must be gently updated to support byte access instead of word access.

2025-01-15Input: i8042 - Add support for platform filter contextsArmin Wolf
Currently the platform filter cannot access any driver-specific state which forces drivers installing a i8042 filter to have at least some kind of global pointer for their filter. Allow callers of i8042_install_filter() to submit a context pointer which is then passed to the i8042 filter. This frees drivers from the responsibility of having to manage this global pointer themself. Also introduce a separate type for the i8042 filter (i8042_filter_t) so that the function definitions can stay compact. Tested on a Dell Inspiron 3505.

2025-01-14Input: Use str_enable_disable-like helpersKrzysztof Kozlowski
Replace ternary (condition ? "enable" : "disable") syntax with helpers from string_choices.h because: 1. Simple function call with one argument is easier to read. Ternary operator has three arguments and with wrapping might lead to quite long code. 2. Is slightly shorter thus also easier to read. 3. It brings uniformity in the text - same string. 4. Allows deduping by the linker, which results in a smaller binary file.

2024-10-15Input: switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/input/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in a few drivers.

2024-09-27[tree-wide] finally take no_llseek outAl Viro
no_llseek had been defined to NULL two years ago, in commit 868941b14441 ("fs: remove no_llseek") To quote that commit, At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\<no_llseek\>/d' $i done would do it. Unfortunately, that hadn't been done. Linus, could you do that now, so that we could finally put that thing to rest? All instances are of the form .llseek = no_llseek, so it's obviously safe.

2024-08-04Input: uinput - reject requests with unreasonable number of slotsDmitry Torokhov
From: Dmitry Torokhov <dmitry.torokhov@gmail.com> When exercising uinput interface syzkaller may try setting up device with a really large number of slots, which causes memory allocation failure in input_mt_init_slots(). While this allocation failure is handled properly and request is rejected, it results in syzkaller reports. Additionally, such request may put undue burden on the system which will try to free a lot of memory for a bogus request. Fix it by limiting allowed number of slots to 100. This can easily be extended if we see devices that can track more than 100 contacts.
