Re: [PATCH v2] can: mcp251xfd: replace sizeof(u32) with val_bytes in regmap

The sizeof(u32) is hardcoded. IMO it's better to use the config value in

I got why you want to change this. Please update the patch description, comment
on the increase of the object size and address the other issues I pointed out.
I think it makes no sense to have the function mcp251xfd_get_val_bytes() as you
have to use several regmaps anyways.
