[ Upstream commit 68e4f01fddb4ead80e8c7084db489307f22c9cbb ]
Before the offending commit in msm_atomic_commit_tail wait_flush was
called once per frame, after the commit was submitted. After it
wait_flush is also called at the beginning to ensure previous
potentially async commits are done.
For cmd panels the source of wait_flush is a ping-pong irq notifying
a completion. The completion needs to be notified with complete_all so
multiple waiting parties (new async committers) can proceed.
