[PATCH v3 09/24] drm/panel: tdo-tl070wsh30: Stop tracking prepared

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



As talked about in commit d2aacaf07395 ("drm/panel: Check for already
prepared/enabled in drm_panel"), we want to remove needless code from
panel drivers that was storing and double-checking the
prepared/enabled state. Even if someone was relying on the
double-check before, that double-check is now in the core and not
needed in individual drivers.

Changes in v2:
- Only handle 1 panel per patch.
- Split removal of prepared/enabled from handling of remove/shutdown.
