From: Ilia Mirkin Date: Fri, 15 Nov 2013 16:26:41 +0000 (-0500) Subject: drm/nv10/plane: fix format computation X-Git-Tag: firefly_0821_release~176^2~4694^2~15 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=92e5b0a2b121c29eac31e6d8106ceefa31de46a9;p=firefly-linux-kernel-4.4.55.git drm/nv10/plane: fix format computation Otherwise none of the format checks pass, since the width was still in 16.16 encoding.
