drm/arm/malidp:- Writeback framebuffer does not support any modifiers
In malidp, the writeback pipeline does not support writing crtc output
to a framebuffer with modifiers ie the memory writeback content is
devoid of any compression or tiling, etc.
So we have added a commit check in memory writeback encoder helper function
to validate if the framebuffer has any modifier and if so, return EINVAL.
Changes since v3 (series):
- Added the ack
- Rebased on the latest drm-misc-next
