2019-01-16input: stpmic1: Add STPMIC1 onkey driverPascal PAILLET-LME
The STPMIC1 pmic is able to manage an onkey button. This driver exposes the STPMIC1 onkey as an input device. It can also be configured to shut-down the power supplies on a long key-press with an adjustable duration.

An integer overflow may arise in uinput_validate_absinfo() if "max - min" can't be represented by an "int". We should check for overflow before trying to use the result.

2019-01-04Input: soc_button_array - fix mapping of the 5th GPIO in a PNP0C40 deviceHans de Goede
The Microsoft documenation for the PNP0C40 device aka the "Windows-compatible button array" describes the 5th GpioInt listed in the resources as: '5. Interrupt corresponding to the "Rotation Lock" button, if supported'. Notice this describes the 5th entry as a button while we sofar have been mapping it to EV_SW, SW_ROTATE_LOCK. On my Point of View TAB P1006W-232 which actually comes with a rotation-lock button, the button indeed is a button and not a slider/switch. An image search for other Windows tablets has found 2 more models with a rotation-lock button and on both of those it too is a push-button and not a slider/switch. Further evidence can be found in the HUT extension HUTRR52 from Microsoft which adds rotation lock support to the HUT, which describes 2 different usages: "0xC9 System Display Rotation Lock Button" and "0xCA System Display Rotation Lock Slider Switch" note that switch is seen as a separate thing here and the non switch wording is an exact match for the "Windows-compatible button array" spec wording. TL;DR: our current mapping of the 5th GPIO to SW_ROTATE_LOCK is wrong because the 5th GPIO is for a push-button not a switch. This commit fixes this by maping the 5th GPIO to KEY_ROTATE_LOCK_TOGGLE.

2018-06-12treewide: devm_kzalloc() -> devm_kcalloc()Kees Cook
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc(). This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...". The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ expression HANDLE; type TYPE; expression THING, E; @@ ( devm_kzalloc(HANDLE, - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | devm_kzalloc(HANDLE, - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression HANDLE;

2018-06-12Input: xen-kbdfront - allow better run-time configurationOleksandr Andrushchenko
It is now only possible to control if multi-touch virtual device is created or not (via the corresponding XenStore entries), but keyboard and pointer devices are always created. In some cases this is not desirable. For example, if virtual keyboard device is exposed to Android then the latter won't automatically show on-screen keyboard as it expects that a physical keyboard device can be used for typing. Utilize keyboard and pointer device XenStore feature fields to configure which virtual devices are created: - set "feature-disable-keyboard" to 1 if no keyboard device needs to be created - set "feature-disable-pointer" to 1 if no pointer device needs to be created Keep old behavior by default.

2018-02-11vfs: do bulk POLL* -> EPOLL* replacementLinus Torvalds
This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2018-01-30Merge branch 'misc.poll' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Pull poll annotations from Al Viro: "This introduces a __bitwise type for POLL### bitmap, and propagates the annotations through the tree. Most of that stuff is as simple as 'make ->poll() instances return __poll_t and do the same to local variables used to hold the future return value'. Some of the obvious brainos found in process are fixed (e.g. POLLIN misspelled as POLL_IN). At that point the amount of sparse warnings is low and most of them are for genuine bugs - e.g. ->poll() instance deciding to return -EINVAL instead of a bitmap. I hadn't touched those in this series - it's large enough as it is. Another problem it has caught was eventpoll() ABI mess; select.c and eventpoll.c assumed that corresponding POLL### and EPOLL### were equal. That's true for some, but not all of them - EPOLL### are arch-independent, but POLL### are not. The last commit in this series separates userland POLL### values from the (now arch-independent) kernel-side ones, converting between them in the few places where they are copied to/from userland. AFAICS, this is the least disruptive fix preserving poll(2) ABI and making epoll() work on all architectures. As it is, it's simply broken on sparc - try to give it EPOLLWRNORM and it will trigger only on what would've triggered EPOLLWRBAND on other architectures. EPOLLWRBAND and EPOLLRDHUP, OTOH, are never triggered at all on sparc.

There is no need to #define the license of the driver, just put it in the MODULE_LICENSE() line directly as a text string. This allows tools that check that the module license matches the source code license to work properly, as there is no need to unwind the unneeded dereference. For some of these drivers, the #define is just a few lines above the MODULE_LICENSE() line, which is extra pointless.

2018-01-09Input: extend usable life of event timestamps to 2106 on 32 bit systemsDeepa Dinamani
The input events use struct timeval to store event time, unfortunately this structure is not y2038 safe and is being replaced in kernel with y2038 safe structures. Because of ABI concerns we can not change the size or the layout of structure input_event, so we opt to re-interpreting the 'seconds' part of timestamp as an unsigned value, effectively doubling the range of values, to year 2106. Newer glibc that has support for 32 bit applications to use 64 bit time_t supplies __USE_TIME_BITS64 define [1], that we can use to present the userspace with updated input_event layout. The updated layout will cause the compile time breakage, alerting applications and distributions maintainers to the issue. Existing 32 binaries will continue working without any changes until 2038. Ultimately userspace applications should switch to using monotonic or boot time clocks, as realtime clock is not very well suited for input event timestamps as it can go backwards (see a80b83b7b8 "Input: evdev - add CLOCK_BOOTTIME support" by by John Stultz). With monotonic clock the practical range of reported times will always fit into the pair of 32 bit values, as we do not expect any system to stay up for a hundred years without a single reboot.

Fix child-node lookup during probe, which ended up searching the whole device tree depth-first starting at parent rather than just matching on its children. Later sanity checks on node properties (which would likely be missing) should prevent this from causing much trouble however, especially as the original premature free of the parent node has already been fixed separately (but that "fix" was apparently never backported to stable).
