[PATCH v1] drm/tegra: plane: Remove format-modifier checking

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

 



Tiling modifier can't be applied to YV12 video overlay because all tiling
modifiers are filtered out for multi-plane formats. AFAIK, all modifiers
should work with all of formats, hence the checking is incorrect and
simply not needed.
