After further introspection of the file drivers/gpu/drm/drm_fourcc.c, I
found that the warning is caused by having the same name for both the
struct and the function as in "const struct drm_format_info
*drm_format_info(u32 format)". This is an issue found using the latest
version of Sphinx as reported by Akira Yokosawa in message id
564cbd05-8788-9223-1ecc-59e7fc41b46a@xxxxxxxxx. So by changing the
function name to something like "query_drm_format_info(u32 format)" is
a possible fix. Question is what should I rename this function to, that
aligns with the coding standards? Also suggest a new function name for
"drm_modeset_lock" that causes the second warning.
