Takashi Iwai 6847b3b6e8 drm/amd/display: Add sanity checks for drm_edid_raw() 
When EDID is retrieved via drm_edid_raw(), it doesn't guarantee to
return proper EDID bytes the caller wants: it may be either NULL (that
leads to an Oops) or with too long bytes over the fixed size raw_edid
array (that may lead to memory corruption).  The latter was reported
actually when connected with a bad adapter.

Add sanity checks for drm_edid_raw() to address the above corner
cases, and return EDID_BAD_INPUT accordingly.

Fixes: 48edb2a425 ("drm/amd/display: switch amdgpu_dm_connector to use struct drm_edid")
