Subject: Re: [PATCH] media: vimc: get pixformat info from v4l2_format_info to
 avoid code repetition

Hi "Carlos,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on linuxtv-media/master]
[cannot apply to v5.4-rc1 next-20191004]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]

base:   git://linuxtv.org/media_tree.git master
reproduce:
        # apt-get install sparse
        # sparse version: v0.6.1-rc1-42-g38eda53-dirty
        make ARCH=x86_64 allmodconfig

sparse warnings: (new ones prefixed by >>)

>> drivers/media/platform/vimc/vimc-common.c:121:21: sparse: sparse: symbol 'vimc_pix_map_fmt_info' was not declared. Should it be static?

Please review and possibly fold the followup patch.
