Subject: USB: move routines in hcd.c
To: Greg KH <[EMAIL PROTECTED]>
Cc: USB development list <linux-usb-devel@lists.sourceforge.net>
Message-ID: <[EMAIL PROTECTED]>
This patch (as939) moves a couple of routine in hcd.c around. The
purpose is to put all the general URB- and endpoint-related routines
(submit, unlink, giveback, and disable) together in one spot.
There are no functional changes.
