Subject: [PATCH 42/51] drm/gm12u320: More drmm_
Date: Fri, 21 Feb 2020 22:03:10 +0100	[thread overview]
Message-ID: <20200221210319.2245170-43-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20200221210319.2245170-1-daniel.vetter@ffwll.ch>

The drm_mode_config_cleanup call we can drop, and all the allocations
we can switch over to drmm_kzalloc. Unfortunately the work queue is
still present, so can't get rid of the drm_driver->release function
outright.
