[PATCH 00/12] drm/amd: Switch over to struct drm_edid

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

 



The AMD DRM drivers use 'struct edid', raw pointers and even custom
structs to represent EDID data.
Uniformly switch to the safe and recommended "struct drm_edid".

Some uses of "struct edid" are left because some ad-hoc parsing is still
being done inside the drivers.

The patch "drm/amd/display: Switch amdgpu_dm_connector to struct drm_edid"
will conflict with my backlight quirk series [0].
The conflict will result in an obvious and easy to fix build failure.

Patches 1 and 2 delete some dead code.
Patches 3 to 6 constify some arguments and shuffle around some code.
The remaining patches perform the actual conversion in steps.
