[PATCH] [media] uvcvideo: Fix build if !MEDIA_CONTROLLER

From: Thierry Reding
Date: Tue Dec 29 2015 - 05:31:21 EST


From: Thierry Reding <treding@xxxxxxxxxx>

Accesses to the UVC device's mdev field need to be protected by a
preprocessor conditional to avoid build errors, since the field is only
included if the MEDIA_CONTROLLER option is selected.

Fixes: 1590ad7b5271 ("[media] media-device: split media initialization and registration")
