Subject: [PATCH 2/3] drm/vc4: Don't disable DSI clocks on component unload.
Date: Wed,  2 Aug 2017 13:32:41 -0700	[thread overview]
Message-ID: <20170802203242.12815-2-eric@anholt.net> (raw)
In-Reply-To: <20170802203242.12815-1-eric@anholt.net>

The clocks are enabled/disabled at encoder enable/disable time, not at
component load.  Fixes a WARN_ON at boot if V3D fails to probe.

Fixes: 4078f5757144 ("drm/vc4: Add DSI driver")
