From bceed1271db7dbaf9ae6649d508f0577f49d4892 Mon Sep 17 00:00:00 2001 From: Anatolij Gustschin Date: Thu, 17 Jan 2013 21:28:37 +0100 Subject: [PATCH] drivers/video: fsl-diu-fb: fix pixel formats for 24 and 16 bpp commit 5d3cc311a76073f6e0a27c0752f7e41f69e95ea7 upstream. Framebuffer colors for 24 and 16 bpp are currently wrong. The order of the color component arguments in the MAKE_PF() is not natural and causes some confusion. The generated pixel format values for 24 and 16 bpp depths do not much the values in the comments. Fix the macro arguments to be in the natural RGB order and adjust the arguments for all depths to generate correct pixel format values (equal to the values mentioned in the comments).
