[PATCH v6 0/2] Fixes for colorspace logic in exynos-gsc and s5p-mfc drivers

[Thibault Saunier <thibault.saunier@osg.samsung.com>]

Hello,

This patchset fixes a few issues on the colorspace logic for the exynos-gsc
and s5p-mfc drivers.

We now handle the colorspace in those drivers, and make sure to respect user setting if
possible.

We also now set the 'v4l2_pix_format:field' if userspace passed ANY, and
replicate users value on the capture side.

This is the sixth version of the patch serie.

Best regards,

Thibault Saunier

Changes in v6:
- Do not ever guess colorspace
- Pass user output field value to the capture as the device is not
  doing any deinterlacing and thus decoded content will still be
  interlaced on the output.

Changes in v5:
- Squash commit to always use output colorspace on the capture side
  inside this one
- Fix typo in commit message
- Just adapt the field and never error out.

Changes in v4:
- Reword commit message to better back our assumptions on specifications

Changes in v3:
- Do not check values in the g_fmt functions as Andrzej explained in previous review
- Added 'Reviewed-by: Andrzej Hajda <a.hajda@samsung.com>'
- Do not check values in the g_fmt functions as Andrzej explained in previous review

Changes in v2:
- Fix a silly build error that slipped in while rebasing the patches
