Input: uinput - add compat ioctl number translation for UI_*_FF_UPLOAD

2019-06-25T03:35:54+00:00

commit 7c7da40da1640ce6814dab1e8031b44e19e5a3f6 upstream.

In the case of compat syscall ioctl numbers for UI_BEGIN_FF_UPLOAD and
UI_END_FF_UPLOAD need to be adjusted before being passed on
uinput_ioctl_handler() since code built with -m32 will be passing
slightly different values. Extend the code already covering
UI_SET_PHYS to cover UI_BEGIN_FF_UPLOAD and UI_END_FF_UPLOAD as well.

Input: synaptics - enable SMBus on ThinkPad E480 and E580

2019-06-25T03:35:54+00:00

commit 9843f3e08e2144724be7148e08d77a195dea257a upstream.

They are capable of using intertouch and it works well with
psmouse.synaptics_intertouch=1, so add them to the list.

Without it, scrolling and gestures are jumpy, three-finger pinch gesture
doesn't work and three- or four-finger swipes sometimes get stuck.

Input: synaptics-rmi4 - fix possible double free

2019-05-16T17:41:25+00:00

[ Upstream commit bce1a78423961fce676ac65540a31b6ffd179e6d ]

The RMI4 function structure has been released in rmi_register_function
if error occurs. However, it will be released again in the function
rmi_create_function, which may result in a double-free bug.

Input: stmfts - acknowledge that setting brightness is a blocking call

2019-05-08T05:21:53+00:00

commit 937c4e552fd1174784045684740edfcea536159d upstream.

We need to turn regulators on and off when switching brightness, and
that may block, therefore we have to set stmfts_brightness_set() as
LED's brightness_set_blocking() method.

Input: snvs_pwrkey - initialize necessary driver data before enabling IRQ

2019-05-08T05:21:53+00:00

commit bf2a7ca39fd3ab47ef71c621a7ee69d1813b1f97 upstream.

SNVS IRQ is requested before necessary driver data initialized,
if there is a pending IRQ during driver probe phase, kernel
NULL pointer panic will occur in IRQ handler. To avoid such
scenario, just initialize necessary driver data before enabling
IRQ. This patch is inspired by NXP's internal kernel tree.

Input: synaptics-rmi4 - write config register values to the right offset

commit 3a349763cf11e63534b8f2d302f2d0c790566497 upstream.

Currently any changed config register values don't take effect, as the
function to write them back is called with the wrong register offset.

Input: soc_button_array - fix mapping of the 5th GPIO in a PNP0C40 device

2019-04-05T20:33:16+00:00

[ Upstream commit e9eb788f9442d1b5d93efdb30c3be071ce8a22b1 ]

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.
