Subject: [PATCH] drm/fourcc: Fix vsub/hsub for Q410 and Q401
Git-commit: b230555f3257f197dd98641ef6ebaf778b52dd51
Patch-mainline: v6.2-rc1
References: git-fixes
These formats are not subsampled, but that means hsub and vsub should be
1, not 0.
Fixes: 94b292b27734 ("drm: drm_fourcc: add NV15, Q410, Q401 YUV formats")
