media: v4l2-dev.h: fix symbol collision in media_entity_to_video_device()
A recent change to the media_entity_to_video_device() macro breaks some use-cases for the macro due to a symbol collision. Before the change this worked: vdev = media_entity_to_video_device(link->sink->entity); While after the change it results in a compiler error "error: 'struct video_device' has no member named 'link'; did you mean 'lock'?". While the following still works after the change. struct media_entity *entity = link->sink->entity; vdev = media_entity_to_video_device(entity); Fix the collision by renaming the macro argument to '__entity'.
