Enumerate entities using MEDIA_ENTITY_ID_FLAG_NEXT
Entity IDs don't have to be contiguous. Use the new flag-based
enumeration system instead of looping over consecutive IDs.

strerror takes a non-negative integer

Don't set formats on remote pads if the remote entity is not a subdev
When setting format on an output pad, the same format is automatically
set on the remote pads, if any. As the format setting API is
subdev-specific, skip remote pads that belong to a non-subdev entity.

Zero structures before filling them
The parse_format function fills a v4l2_mbus_framefmt structure but
doesn't zero it beforehand. This results in some fields being
uninitialized. Fix this.
