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.
