To facilitate easier reviewing this is split out from the overall nonblocking commit rework. It just rolls out the helper functions and uses them in the main drm_atomic_helper_commit() function to make it clear where in the flow they're used. The next patch will actually split drm_atomic_helper_commit() into 2 pieces, with the tail being run asynchronously from a worker. v2: Improve kerneldocs (Maarten). v3: Don't convert ERESTARTSYS to EINTR (Maarten). Also don't fail if the wait succeed in stall_check - we need to convert that case (it returns the remaining jiffies) to 0 for success. v4: Switch to long for wait_for_completion_timeout return value everywhere (Maarten). v5: Fix miscaped function in kerneldoc (Maarten).
