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.
