From 045030fa16648449b416d4fc8dcc54bfefd6f4aa Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Fri, 8 Apr 2011 09:11:43 -0300 Subject: [PATCH] [media] s5p-fimc: Fix bytesperline and plane payload setup Make sure the sizeimage for 3-planar color formats is width * height * 3/2 and the bytesperline is same for each plane in case of a multi-planar format.
