Hi all,

After merging the drm-msm tree, today's linux-next build (arm64
defconfig) failed like this:

/tmp/next/build/drivers/gpu/drm/msm/msm_ringbuffer.c: In function 'msm_ringbuffer_new':
/tmp/next/build/drivers/gpu/drm/msm/msm_ringbuffer.c:104:29: error: passing argument 7 of 'drm_sched_init' from incompatible pointer type [-Werror=incompatible-pointer-types]

cc1: some warnings being treated as errors

Probably caused by commit

  1d8a5ca436ee4a28ee ("drm/msm: Conversion to drm scheduler")

Since there was previously nothing in the drm-msm tree I've just dropped
the branch.
