[PATCH 08/12] drm/amdgpu: Switch amdgpu_connector to struct drm_edid

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

 



"struct drm_edid" is the safe and recommended alternative to "struct edid".

Rename the member to make sure that no usage sites are missed,
as "struct drm_edid" has some restrictions, for example it can not be
used with kfree().
