Subject: linux-next: manual merge of the usb tree with the v4l-dvb tree
Hi Greg,
Today's linux-next merge of the usb tree got a conflict in
drivers/media/video/uvc/uvcvideo.h include/linux/usb/video.h between
commits c3810b43416155d040a200e7a7301f379c8ae8a0 ("V4L/DVB: uvcvideo:
Support menu controls in the control mapping API") and
da1df555fcbb98a9d2054304ea54545d9ff523cf ("V4L/DVB: uvcvideo: Define
control information bits using macros") from the v4l-dvb tree and commit
bb03b5daa9ab053adcce09e939d4115a873abf39 ("USB: uvc: Move constants and
structures definitions to linux/usb/video.h") from the usb tree.
I fixed it up (see below) and can carry the fix as necessary. Though
moving the USB patch into the v4l-dvb tree may fix the conflicts as
well ...

Cheers,
