Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input fixes from Dmitry Torokhov: "Just a few small fixups here" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: imx_sc_key - only take the valid data from SCU firmware as key state Input: add safety guards to input_set_keycode() Input: input_event - fix struct padding on sparc64 Input: uinput - always report EPOLLOUT

Input: imx_sc_key - only take the valid data from SCU firmware as key state

2019-12-14T00:41:57Z

When reading key state from SCU, the response data from SCU firmware is 4 bytes due to MU message protocol, but ONLY the first byte is the key state, other 3 bytes could be some dirty data, so we should ONLY take the first byte as key state to avoid reporting incorrect state.

Input: snvs_pwrkey - remove gratuitous NULL initializers

2019-12-05T01:56:55Z

Gratuitous NULL initializers rarely help and often prevent compiler from warning about using uninitialized variable. Let's remove them. Reviewed-by: Anson Huang Link: https://lore.kernel.org/r/20191125211407.GA97812@dtor-ws Signed-off-by: Dmitry Torokhov

Input: snvs_pwrkey - send key events for i.MX6 S, DL and Q

2019-11-25T21:32:11Z

The first generation i.MX6 processors does not send an interrupt when the power key is pressed. It sends a power down request interrupt if the key is released before a hard shutdown (5 second press). This should allow software to bring down the SoC safely. For this driver to work as a regular power key with the older SoCs, we need to send a keypress AND release when we get the power down request irq.

Input: imx_sc_key - correct SCU message structure to avoid stack corruption

2019-11-15T19:49:29Z

The SCU message's data field used for receiving response data from SCU should be 32-bit width, as SCU will send back 32-bit width data. This solves kernel panic when CONFIG_CC_HAVE_STACKPROTECTOR_SYSREG is enabled.
