That solves several merge conflicts: Documentation/DocBook/media/v4l/subdev-formats.xml Documentation/devicetree/bindings/vendor-prefixes.txt drivers/staging/media/mn88473/mn88473.c include/linux/kconfig.h include/uapi/linux/media-bus-format.h The ones at subdev-formats.xml and media-bus-format.h are not trivial. That's why we opted to merge from DRM.
| * of: Decrement refcount of previous endpoint in of_graph_get_next_endpointPhilipp Zabel2015-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Decrementing the reference count of the previous endpoint node allows to use the of_graph_get_next_endpoint function in a for_each_... style macro. All current users of this function that pass a non-NULL prev parameter (that is, soc_camera and imx-drm) are changed to not decrement the passed prev argument's refcount themselves.

| | | | | | | | | | | | | | | | | | | | | | Embed video_device struct (video_dev) in vpfe_device and Unregister path doesn't need to free the video_device structure, hence, change the video_device.release callback point to video_device_release_empty.

* | [media] media: am437x: Don't release OF node reference twiceLaurent Pinchart2015-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The remote port reference is released both at the end of the OF graph parsing loop, and in the error code path at the end of the function. Those two calls will release the same reference, causing the reference count to go negative. Fix the problem by removing the second call.
