pointer to struct v4l2_pix_format to be filled
const struct v4l2_mbus_framefmt *mbus_fmt
pointer to struct v4l2_mbus_framefmt to be used as model
void v4l2_fill_mbus_format(struct v4l2_mbus_framefmt *mbus_fmt, const struct v4l2_pix_format *pix_fmt, u32 code)

Ancillary routine that fills a struct v4l2_mbus_framefmt from a struct v4l2_pix_format and a data format code.

Parameters

struct v4l2_mbus_framefmt *mbus_fmt
pointer to struct v4l2_mbus_framefmt to be filled
const struct v4l2_pix_format *pix_fmt
pointer to struct v4l2_pix_format to be used as model
u32 code
data format code (from enum v4l2_mbus_pixelcode)
