2021-10-16Input: touchscreen - avoid bitwise vs logical OR warningNathan Chancellor1-21/+21
A new warning in clang points out a few places in this driver where a bitwise OR is being used with boolean types: drivers/input/touchscreen.c:81:17: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical] data_present = touchscreen_get_prop_u32(dev, "touchscreen-min-x", ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This use of a bitwise OR is intentional, as bitwise operations do not short circuit, which allows all the calls to touchscreen_get_prop_u32() to happen so that the last parameter is initialized while coalescing the results of the calls to make a decision after they are all evaluated. To make this clearer to the compiler, use the '|=' operator to assign the result of each touchscreen_get_prop_u32() call to data_present, which keeps the meaning of the code the same but makes it obvious that every one of these calls is expected to happen.

2021-10-16Input: snvs_pwrkey - add clk handlingUwe Kleine-König1-0/+29
On i.MX7S and i.MX8M* (but not i.MX6*) the pwrkey device has an associated clock. Accessing the registers requires that this clock is enabled. Binding the driver on at least i.MX7S and i.MX8MP while not having the clock enabled results in a complete hang of the machine. (This usually only happens if snvs_pwrkey is built as a module and the rtc-snvs driver isn't already bound because at bootup the required clk is on and only gets disabled when the clk framework disables unused clks late during boot.) This completes the fix in commit 135be16d3505 ("ARM: dts: imx7s: add snvs clock to pwrkey").

2021-07-21bus: Make remove callback return voidUwe Kleine-König2-4/+2
The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

2021-07-05Input: joydev - prevent use of not validated data in JSIOCSBTNMAP ioctlAlexander Larkin1-1/+1
Even though we validate user-provided inputs we then traverse past validated data when applying the new map. The issue was originally discovered by Murray McAllister with this simple POC (if the following is executed by an unprivileged user it will instantly panic the system): int main(void) { int fd, ret; unsigned int buffer[10000]; fd = open("/dev/input/js0", O_RDONLY); if (fd == -1) printf("Error opening file\n"); ret = ioctl(fd, JSIOCSBTNMAP & ~IOCSIZE_MASK, &buffer); printf("%d\n", ret); } The solution is to traverse internal buffer which is guaranteed to only contain valid date when constructing the map. Fixes: 182d679b2298 ("Input: joydev - prevent potential read overflow in ioctl") Fixes: 999b874f4aa3 ("Input: joydev - validate axis/button maps before clobbering current ones") Reported-by: Murray McAllister <murray.mcallister@gmail.com> Suggested-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Alexander Larkin <avlarkin82@gmail.com> Link: https://lore.kernel.org/r/20210620120030.1513655-1-avlarkin82@gmail.com Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
