2011-10-25uvcvideo: Fix crash when linking entitiesLaurent Pinchart
commit 4d9b2ebd335d83044b9e6656d0e604e8e1300334 upstream. The uvc_mc_register_entity() function wrongfully selects the media_entity associated with a UVC entity when creating links. This results in access to uninitialized media_entity structures and can hit a BUG_ON statement in media_entity_create_link(). Fix it.

2011-06-30[media] uvcvideo: Ignore entities for terminals with no supported formatLaurent Pinchart
If a streaming interface has no supported format, the driver won't create a video device for the associated terminal. Fix an oops by ignoring that terminal when creating links between entities.
