Subject: [PATCH v3] media: vimc: get pixformat info from v4l2_format_info

From: "Carlos E.C. Barbosa" <[email protected]>

There is overlapping code over two distinct lists. This repurposes vimc_pix_map
for mapping formats and remaps the calls to the matching v4l2_format_info.

---
Changes in v2:
As advised by Helen Koike and Hans Verkuil, the const qualifiers are not
removed, the bayer flag is kept and the unnecessary changes are not
made.

Changes in v3:
Change declaration order of variables and some minor style changes.

v4l2-compliance message:

This Sob needs to be above the --- line!

I get sparse warnings:

drivers/media/platform/vimc/vimc-scaler.c:128:33: warning: variable 'vinfo' set but not used [-Wunused-but-set-variable]
drivers/media/platform/vimc/vimc-scaler.c:181:33: warning: variable 'vinfo' set but not used [-Wunused-but-set-variable]

It does seem that it is indeed unused.

Regards,

Hans
