Input: hideep - fix the uninitialized use in hideep_nvm_unlock()

[ Upstream commit cac7100d4c51c04979dacdfe6c9a5e400d3f0a27 ] Inside function hideep_nvm_unlock(), variable "unmask_code" could be uninitialized if hideep_pgm_r_reg() returns error, however, it is used in the later if statement after an "and" operation, which is potentially unsafe.

m68k: atari: Fix ATARI_KBD_CORE kconfig unmet dependency warning

[ Upstream commit c1367ee016e3550745315fb9a2dd1e4ce02cdcf6 ] Since the code for ATARI_KBD_CORE does not use drivers/input/keyboard/ code, just move ATARI_KBD_CORE to arch/m68k/Kconfig.machine to remove the dependency on INPUT_KEYBOARD.

Input: goodix - platform/x86: touchscreen_dmi - Move upside down quirks to touchscreen_dmi.c

2021-07-14T14:55:57+00:00

[ Upstream commit 5a6f0dbe621a5c20dc912ac474debf9f11129e03 ] Move the DMI quirks for upside-down mounted Goodix touchscreens from drivers/input/touchscreen/goodix.c to drivers/platform/x86/touchscreen_dmi.c, where all the other x86 touchscreen quirks live. Note the touchscreen_dmi.c code attaches standard touchscreen device-properties to an i2c-client device based on a combination of a DMI match + a device-name match. I've verified that the: Teclast X98 Pro, WinBook TW100 and WinBook TW700 uses an ACPI devicename of "GDIX1001:00" based on acpidumps and/or dmesg output available on the web. This patch was tested on a Teclast X89 tablet. Signed-off-by: Hans de Goede Link: https://lore.kernel.org/r/20210504185746.175461-2-hdegoede@redhat.com Signed-off-by: Sasha Levin

Input: joydev - prevent use of not validated data in JSIOCSBTNMAP ioctl

2021-07-14T14:55:39+00:00

commit f8f84af5da9ee04ef1d271528656dac42a090d00 upstream. 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.

commit 41e81022a04a0294c55cfa7e366bc14b9634c66e upstream.

Input: silead - add workaround for x86 BIOS-es which bring the chip up in a stuck state

2021-05-22T09:40:52+00:00

[ Upstream commit e479187748a8f151a85116a7091c599b121fdea5 ] Some buggy BIOS-es bring up the touchscreen-controller in a stuck state where it blocks the I2C bus. Specifically this happens on the Jumper EZpad 7 tablet model. After much poking at this problem I have found that the following steps are necessary to unstuck the chip / bus: 1. Turn off the Silead chip. 2. Try to do an I2C transfer with the chip, this will fail in response to which the I2C-bus-driver will call: i2c_recover_bus() which will unstuck the I2C-bus. Note the unstuck-ing of the I2C bus only works if we first drop the chip of the bus by turning it off. 3. Turn the chip back on. On the x86/ACPI systems were this problem is seen, step 1. and 3. require making ACPI calls and dealing with ACPI Power Resources. This commit adds a workaround which runtime-suspends the chip to turn it off, leaving it up to the ACPI subsystem to deal with all the ACPI specific details. There is no good way to detect this bug, so the workaround gets activated by a new "silead,stuck-controller-bug" boolean device-property. Since this is only used on x86/ACPI, this will be set by model specific device-props set by drivers/platform/x86/touchscreen_dmi.c. Therefor this new device-property is not documented in the DT-bindings. Dmesg will contain the following messages on systems where the workaround is activated: [ 54.309029] silead_ts i2c-MSSL1680:00: [Firmware Bug]: Stuck I2C bus: please ignore the next 'controller timed out' error [ 55.373593] i2c_designware 808622C1:04: controller timed out [ 55.582186] silead_ts i2c-MSSL1680:00: Silead chip ID: 0x80360000 Signed-off-by: Hans de Goede Link: https://lore.kernel.org/r/20210405202745.16777-1-hdegoede@redhat.com Signed-off-by: Dmitry Torokhov Signed-off-by: Sasha Levin
