drm: Use device_get_match_data()

2023-11-27T19:56:32+00:00

Use preferred device_get_match_data() instead of of_match_device() to get the driver match data in a single step. With this, adjust the includes to explicitly include the correct headers. That also serves as preparation to remove implicit includes within the DT headers (of_device.h in particular).

drm/omap: Convert to platform remove callback returning void

2023-06-08T17:35:17+00:00

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert the omap drm driver from always returning zero in the remove callback to the void returning variant.

drm_crtc.h has no need for drm_edid.h, so don't include it. Avoids useless rebuilds of the entire universe when touching drm_edid.h. Quite a few placs do currently depend on drm_edid.h without actually including it directly.
