  While updating v4l2_create_fwnode_links_to_pad() to accept non-subdev
sinks, the check is_media_entity_v4l2_subdev() was not removed which
prevented the function from being used with non-subdev sinks, Drop the
unnecessary check.

Fixes: bd5a03bc5be8 ("media: Accept non-subdev sinks in v4l2_create_fwnode_links_to_pad()")

Sakari, the commit this patch fixes will land in v6.4, should this be
merged as a v6.4 fix ?

I'd think so. I'll take this soonish.
