drm/modes: Make width-mm/height-mm check in of_get_drm_panel_display_mode() mandatory

2022-04-24T21:54:05+00:00

All users of this function require width-mm/height-mm DT property to be present per their DT bindings, make width-mm/height-mm check mandatory. It is generally a good idea to specify panel dimensions, so userspace can configure e.g. scaling accordingly.

drm: Use drm_mode_init() for on-stack modes

2022-04-12T06:26:08+00:00

Initialize on-stack modes with drm_mode_init() to guarantee no stack garbage in the list head, or that we aren't copying over another mode's list head.

drm: Add drm_mode_init()

2022-03-14T15:36:59+00:00

Add a variant of drm_mode_copy() that explicitly clears out the list head of the destination mode. Helpful to guarantee we don't have stack garbage left in there for on-stack modes.
