[PATCH 0/3] Add missing format_mod_supported functions

From: José Expósito

Hi all,

When setting IN_FORMATS, implementing the
"drm_plane_funcs.format_mod_supported" function is mandatory to avoid
exposing a bogus blob.

This patchset adds a bit of documentation and fixes the issue in a
couple of drivers affected by the bug.

I reviewed all the other drivers and I didn't find more instances of
the issue.
