static int alvium_enum_mbus_code(struct v4l2_subdev *sd,
Inline alvium_set_frame_interval() into alvium_s_frame_interval(). The alvium_set_frame_interval() is called once only, by alvium_s_frame_interval(). The latter is a thin wrapper around the former. Inline the function in its caller to make the code more readable.
