[PATCH 5/9] drm/msm: convert kms->complete_commit() to crtc_mask

Rob Clark
2019-08-27T21:48:13Z

Prep work for async commits, in which case this will be called after we
no longer have the atomic state object.

This drops some wait_for_vblanks(), but those should be unnecessary, as
we call this after waiting for flush to complete.
