2022-09-26clk: mediatek: clk-apmixed: Add helper function to unregister ref2usb_txAngeloGioacchino Del Regno
The ref2usb_tx clock was introduced a long time ago and, at that time, the MediaTek clock drivers were using CLK_OF_DECLARE, so they would never unregister. Nowadays, unregistering clock drivers is a thing, as we're registering them as platform_driver and allowing them to be kernel modules: add a helper function to cleanup the ref2usb_tx clock during error handling and upon module removal.

2022-09-26drm/exynos: Fix return type for mixer_mode_valid and hdmi_mode_validNathan Huckleberry
The field mode_valid in exynos_drm_crtc_ops is expected to be of type enum drm_mode_status (*mode_valid)(struct exynos_drm_crtc *crtc, const struct drm_display_mode *mode); Likewise for mode_valid in drm_connector_helper_funcs. The mismatched return type breaks forward edge kCFI since the underlying function definition does not match the function hook definition. The return type of mixer_mode_valid and hdmi_mode_valid should be changed from int to enum drm_mode_status.

2022-09-25hwmon: (vt8231) Introduce a #define for the driver name and use itUwe Kleine-König
Make use of the cpp symbol DRIVER_NAME to set the driver's name and use it instead of all explicit usages of the same string. Also make use of it instead of vt8231_driver.driver.name which breaks a cyclic dependency between vt8231_probe() and vt8231_driver that in the next commit allows to drop some forward declarations.

2022-09-25hwmon: (pc87360) Introduce a #define for the driver name and use itUwe Kleine-König
Make use of the cpp symbol DRIVER_NAME to set the driver's name and also as name for devm_request_region(). While at it add a module alias using the new define. This is a preparation for the next cleanup commit that removes a cyclic dependency between pc87360_driver (which references pc87360_probe in .probe) and pc87360_probe() (which used pc87360_driver.driver.name).

2022-09-25hwmon: (pwm-fan) Switch regulator dynamicallyAlexander Stein
This adds the enable attribute which is used to select if zero PWM duty means to switch off regulator and PWM or to keep them enabled but at inactive PWM output level. Depending on the select enable mode, turn off the regulator and PWM if the PWM duty is zero, or keep them enabled. This is especially important for fan using inverted PWM signal polarity. Having regulator supplied and PWM disabled, some PWM controllers provide the active, rather than inactive signal. With this change the shutdown as well as suspend/resume paths require modifcations as well.

2022-09-25hwmon: (pwm-fan) split __set_pwm into locked/unlocked functionsAlexander Stein
Regular calls to set_pwm don't hold the mutex, but the upcoming update_enable support needs to call set_pwm with the mutex being held. So provide the previous behavior in set_pwm (handling the lock), while adding __set_pwm which assumes the lock being held.

2022-09-25hwmon: (pwm-fan) Add dedicated power switch functionAlexander Stein
This handles enabling/disabling the regulator in a single function, while keeping the enables/disabled balanced. This is a preparation when regulator is switched from different code paths.

2022-09-25hwmon: (pwm-fan) Simplify enable/disable checkAlexander Stein
Instead of comparing the current to the new pwm duty to decide whether to enable the PWM, use a dedicated flag. Also apply the new PWM duty in any case. This is a preparation to enable/disable the regulator dynamically.
