-Subject: [PATCH] drm/vc4: Correct handling of rotation parameter in
- fkms
-
-One bit within DRM_MODE_ROTATE_MASK will always be set to
-determine the base rotation 0/90/180/270, and then REFLECT_X
-and REFLECT_Y are on top.
-
-Correct the handling which was assuming that REFLECT_[X|Y]
-was instead of ROTATE_x.
