From: Laurent Pinchart Date: Wed, 27 May 2015 23:39:35 +0000 (+0300) Subject: drm: omapdrm: Don't flush CRTC when enabling or disabling it X-Git-Tag: firefly_0821_release~176^2~1437^2^2~14 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=af6da31e9c8d25f4be524c2bf97a886071eb4a00;p=firefly-linux-kernel-4.4.55.git drm: omapdrm: Don't flush CRTC when enabling or disabling it The omap_crtc_flush() call in omap_crtc_enable() and omap_crtc_disable() is a no-op, as the display manager is always disabled at this point. Just remove the function call.
