Subject: [PATCH 10/32] drm/nouveau: Fix crtc->primary->fb vs. drm_fb fail
Date: Thu, 17 Nov 2016 18:14:09 +0200	[thread overview]
Message-ID: <1479399271-31991-11-git-send-email-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <1479399271-31991-1-git-send-email-ville.syrjala@linux.intel.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

So it looks like the code is trying to pick between the passed in fb and
crtc->primary->fb based on that funky 'bool atomic'. But later it will
mix uses of both drm_fb (which was picked by the aforementioned logic)
and crtc->primary->fb. So looks like a bug to me. Let's make it use
drm_fb only.
