Merge tag 'usb-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB changes from Greg Kroah-Hartman: "Here is the big USB pull request for 3.7-rc1 There are lots of gadget driver changes (including copying a bunch of files into the drivers/staging/ccg/ directory so that the other gadget drivers can be fixed up properly without breaking that driver), and we remove the old obsolete ub.c driver from the tree. There are also the usual XHCI set of updates, and other various driver changes and updates. We also are trying hard to remove the old dbg() macro, but the final bits of that removal will be coming in through the networking tree before we can delete it for good. All of these patches have been in the linux-next tree. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>" Fix up several annoying - but fairly mindless - conflicts due to the termios structure having moved into the tty device, and often clashing with dbg -> dev_dbg conversion. * tag 'usb-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (339 commits) USB: ezusb: move ezusb.c from drivers/usb/serial to drivers/usb/misc USB: uas: fix gcc warning USB: uas: fix locking USB: Fix race condition when removing host controllers USB: uas: add locking USB: uas: fix abort USB: uas: remove aborted field, replace with status bit.
