2024-09-02reset: core: add get_device()/put_device on rcdevClément Léger
Since the rcdev structure is allocated by the reset controller drivers themselves, they need to exists as long as there is a consumer. A call to module_get() is already existing but that does not work when using device-tree overlays. In order to guarantee that the underlying reset controller device does not vanish while using it, add a get_device() call when retrieving a reset control from a reset controller device and a put_device() when releasing that control.

2024-09-02gpio: stmpe: Simplify with dev_err_probe()Shen Lichuan
Use dev_err_probe() to simplify the error path and unify a message template. Using this helper is totally fine even if err is known to never be -EPROBE_DEFER. The benefit compared to a normal dev_err() is the standardized format of the error code, it being emitted symbolically and the fact that the error code is returned which allows more compact error paths.

2024-09-02pinctrl: qcom: x1e80100: Bypass PDC wakeup parent for nowStephan Gerhold
On X1E80100, GPIO interrupts for wakeup-capable pins have been broken since the introduction of the pinctrl driver. This prevents keyboard and touchpad from working on most of the X1E laptops. So far we have worked around this by manually building a kernel with the "wakeup-parent" removed from the pinctrl node in the device tree, but we cannot expect all users to do that. Implement a similar workaround in the driver by clearing the wakeirq_map for X1E80100. This avoids using the PDC wakeup parent for all GPIOs and handles the interrupts directly in the pinctrl driver instead. The PDC driver needs additional changes to support X1E80100 properly. Adding a workaround separately first allows to land the necessary PDC changes through the normal release cycle, while still solving the more critical problem with keyboard and touchpad on the current stable kernel versions. Bypassing the PDC is enough for now, because we have not yet enabled the deep idle states where using the PDC becomes necessary.

2024-09-02ALSA: core: Drop superfluous no_free_ptr() for memdup_user() errorsTakashi Iwai
We used to wrap with no_free_ptr() for the return value from memdup_user() with errors where the auto cleanup is applied. This was a workaround because the initial implementation of kfree auto-cleanup checked only NULL pointers. Since recently, though, the kfree auto-cleanup checks with IS_ERR_OR_NULL() (by the commit cd7eb8f83fcf ("mm/slab: make __free(kfree) accept error pointers")), hence those workarounds became superfluous. Let's drop them now. Link: https://patch.msgid.link/20240902075246.3743-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
