Subject: [PATCH 2/4] drm/msm: Mark the crtc->state->event consumed
Date: Tue, 27 Mar 2018 12:31:52 -0400	[thread overview]
Message-ID: <20180327163154.40374-3-seanpaul@chromium.org> (raw)
In-Reply-To: <20180327163154.40374-1-seanpaul-F7+t8E8rja9g9hUCZPvPmw@public.gmane.org>

Don't leave the event != NULL once it's consumed, this is used a signal
to the atomic helpers that the event will be handled by the driver.
