Subject: [PATCH v2 11/15] drm/radeon: Turn off CRTCs on driver unload
Date: Wed, 8 Jun 2016 18:47:27 +0200	[thread overview]
Message-ID: <f706b9db319e2bdaf153966a2b95a5d80f67e09b.1465392124.git.lukas@wunner.de> (raw)
In-Reply-To: <cover.1465392124.git.lukas@wunner.de>

radeon leaks a runtime pm ref if at least one CRTC is enabled on unload.
The ref is taken by radeon_crtc_set_config() and held as long as a CRTC
is in use. Fix by turning off all CRTCs on unload.
