Now there are no users of the return value of the drm_panel_prepare(), drm_panel_unprepare(), drm_panel_enable() and drm_panel_disable() calls. Usually these calls are performed from the atomic callbacks, where it is impossible to return an error. Stop returning error codes and return void instead.

2025-04-22drm: panel: jd9365da: fix reset signal polarity in unprepareHugo Villeneuve
commit a8972d5a49b4 ("drm: panel: jd9365da-h3: fix reset signal polarity") fixed reset signal polarity in jadard_dsi_probe() and jadard_prepare(). It was not done in jadard_unprepare() because of an incorrect assumption about reset line handling in power off mode. After looking into the datasheet, it now appears that before disabling regulators, the reset line is deasserted first, and if reset_before_power_off_vcioo is true, then the reset line is asserted. Fix reset polarity by inverting gpiod_set_value() second argument in in jadard_unprepare().

2025-02-13drm: panel: jd9365da-h3: fix reset signal polarityHugo Villeneuve
In jadard_prepare() a reset pulse is generated with the following statements (delays ommited for clarity): gpiod_set_value(jadard->reset, 1); --> Deassert reset gpiod_set_value(jadard->reset, 0); --> Assert reset for 10ms gpiod_set_value(jadard->reset, 1); --> Deassert reset However, specifying second argument of "0" to gpiod_set_value() means to deassert the GPIO, and "1" means to assert it. If the reset signal is defined as GPIO_ACTIVE_LOW in the DTS, the above statements will incorrectly generate the reset pulse (inverted) and leave it asserted (LOW) at the end of jadard_prepare(). Fix reset behavior by inverting gpiod_set_value() second argument in jadard_prepare(). Also modify second argument to devm_gpiod_get() in jadard_dsi_probe() to assert the reset when probing. Do not modify it in jadard_unprepare() as it is already properly asserted with "1", which seems to be the intended behavior.
