From cf52df8acfda9442d64ab4d3d6085877f6d88d46 Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Mon, 13 Jun 2011 11:09:40 -0300 Subject: [PATCH] [media] s5p-fimc: Correct color format enumeration Replace fimc_find_format() and find_mbus_format() with single function that can return a pointer to the private format description based on fourcc, media bus code or index in the table. Create separate VIDIOC_ENUM_FMT ioctl handlers for video capture and mem-to-mem video node. This is needed because some formats are valid only for the video capture and some only for the mem-to-mem video node.
