From e1dedcfff1bbaa6b56a40116ee402b6d222e20c9 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 31 May 2015 07:51:51 -0300 Subject: [media] cobalt: simplify colorspace code Simplify cobalt_g/try_fmt_vid_cap by not setting the colorspace fields in pix again (since v4l2_fill_pix_format does that already), and by using v4l2_fill_mbus_format in cobalt_s_fmt_vid_out which allows the get_fmt call to be dropped as well.
