X-Git-Tag: v2013.10-rc1~53^2~11
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ab52df19c1195699516430be14b6be2d27229444;p=platform%2Fkernel%2Fu-boot.git

usb: mv_udc: Move QH and qTD into mv_drv

Both the endpoint queue head and the endpoint item list is a controller
specific thing. Move them both into controller private data.
