Subject: [PATCH 07/10] drm/vkms: Dont flush crc worker when we change crc status
Date: Fri,  7 Jun 2019 00:27:48 +0200	[thread overview]
Message-ID: <20190606222751.32567-8-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20190606222751.32567-1-daniel.vetter@ffwll.ch>

The crc core code can cope with some late crc, the race is kinda
unavoidable. So no need to flush pending workers, they'll complete in
time.
