Subject: Re: [PATCH v12 09/15] drm/vkms: Remove useless drm_rotation_simplify


Hi all,

Until this point, this series has not received any major comments since 
v9. I will commit patches 1-9 next week if there are no further comments.

For patches 10-15, I am currently waiting for feedback from Maxime to 
send the next iteration with a fix for kunit tests.

Thanks,
Louis Chauvet
