From 84a093a9e74b52bce8f8abb65a1c9e4c89ea1060 Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Thu, 20 Jun 2013 10:49:09 -0300 Subject: [PATCH] [media] exynos4-is: Correct colorspace handling at FIMC-LITE Ensure the colorspace is properly adjusted by the driver for YUV and Bayer image formats. The subdev try_fmt helper is simplified.
