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

Fixes: e90124cb46bdb ("drm/tegra: plane: Support format modifiers")
