Input: pm8xxx-vibrator - correct VIB_MAX_LEVELS calculation

2024-06-12T09:12:37+00:00

[ Upstream commit 48c0687a322d54ac7e7a685c0b6db78d78f593af ]

The output voltage is inclusive hence the max level calculation is
off-by-one-step. Correct it.

iWhile we are at it also add a define for the step size instead of
using the magic value.

Input: ims-pcu - fix printf string overflow

[ Upstream commit bf32bceedd0453c70d9d022e2e29f98e446d7161 ]

clang warns about a string overflow in this driver

drivers/input/misc/ims-pcu.c:1802:2: error: 'snprintf' will always be truncated; specified size is 10, but format string expands to at least 12 [-Werror,-Wformat-truncation]
drivers/input/misc/ims-pcu.c:1814:2: error: 'snprintf' will always be truncated; specified size is 10, but format string expands to at least 12 [-Werror,-Wformat-truncation]

Make the buffer a little longer to ensure it always fits.

pwm: Rename pwm_apply_state() to pwm_apply_might_sleep()

2024-06-12T09:12:24+00:00

[ Upstream commit c748a6d77c06a78651030e17da6beb278a1c9470 ]

In order to introduce a pwm api which can be used from atomic context,
we will need two functions for applying pwm changes:

	int pwm_apply_might_sleep(struct pwm *, struct pwm_state *);
	int pwm_apply_atomic(struct pwm *, struct pwm_state *);

This commit just deals with renaming pwm_apply_state(), a following
commit will introduce the pwm_apply_atomic() function.

Input: soc_button_array - add mapping for airplane mode button

2024-01-01T12:42:41+00:00

commit ea3715941a9b7d816a1e9096ac0577900af2a69e upstream.

This add a mapping for the airplane mode button on the TUXEDO Pulse Gen3.

While it is physically a key it behaves more like a switch, sending a key
down on first press and a key up on 2nd press. Therefor the switch event
is used here. Besides this behaviour it uses the HID usage-id 0xc6
(Wireless Radio Button) and not 0xc8 (Wireless Radio Slider Switch), but
since neither 0xc6 nor 0xc8 are currently implemented at all in
soc_button_array this not to standard behaviour is not put behind a quirk
for the moment.

Merge tag 'input-for-v6.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

2023-10-14T06:19:16+00:00

Pull input fixes from Dmitry Torokhov:

 - a reworked way for handling reset delay on SMBus-connected Synaptics
   touchpads (the original one, while being correct, uncovered an old
   bug in fallback to PS/2 code that was fixed separately; the new one
   however avoids having delay in serio port "fast" resume, and instead
   has the wait in the RMI4 code)

 - a fix for potential crashes when devices with Elan controllers (and
   Synaptics) fall back to PS/2 code. Can't be hit without the original
   patch above, but still good to have it fixed

 - a couple new device IDs in xpad Xbox driver

 - another quirk for Goodix driver to deal with stuff vendors put in
   ACPI tables

 - a fix for use-after-free on disconnect for powermate driver

 - a quirk to not initialize PS/2 mouse port on Fujitsu Lifebook E5411
   laptop as it makes keyboard not usable and the device uses
   hid-over-i2c touchpad anyways

2023-10-14T03:17:02+00:00

syzbot has found a use-after-free bug [1] in the powermate driver. This
happens when the device is disconnected, which leads to a memory free from
the powermate_device struct.  When an asynchronous control message
completes after the kfree and its callback is invoked, the lock does not
exist anymore and hence the bug.

Use usb_kill_urb() on pm->config to cancel any in-progress requests upon
device disconnection.
