I think you could keep vpix a pointer (please see below).

If vpix is a pointer, then this still need to be checked.

This is nice to cache the info inside the vpix.
What you could to is to have info to be of type const struct v4l2_format_info directly.
Something like this:
struct vimc_pix_map_fmt {
unsigned int code;
u32 pixelformat;
const struct v4l2_format_info *info;
};
Then, if (!vpix->info), you fill the pointer, to cache it.
But this means that vimc_pix_map_fmt_list[] can't be const anymore, so I'm not entirely sure,
maybe it is better to call v4l2_format_info() always? hmm, not sure.
In any case, I don't think vimc_pix_map is necessary (please see below).

I don't think you need this function, you already have the code information
inside vimc_pix_map_fmt, why duplicate it?

If you don't have struct vimc_pix_map, you can work with pointers to
struct vimc_pix_map_fmt and struct v4l2_format_info, so you don't need to
do this tricky to return a zeroed struct.

I don't think you need this struct, you can get the info when you need it,
and work with const struct v4l2_format_info *info directly.
Also, you already have the code in the struct vimc_pix_map_fmt above, no need
to duplicate it.

hmm, I just saw we can't do this.
This is bayer too:
{ .format = V4L2_PIX_FMT_SRGGB12, .mem_planes = 1, .comp_planes = 1, .bpp = { 2, 0, 0, 0 }, .hdiv = 1, .vdiv = 1 },
And this is not:
{ .format = V4L2_PIX_FMT_YUYV, .mem_planes = 1, .comp_planes = 1, .bpp = { 2, 0, 0, 0 }, .hdiv = 2, .vdiv = 1 },
I think we'll need to keep the bayer flag :(
I hope this helps,
Let me know if you have any questions
