USB: Dealias -110 code (more complete)
From: Mauro Carvalho Chehab <mchehab@infradead.org>
Apply the relevant parts of a patch from Pete Zaitcev <zaitcev@redhat.com>
kernel-sync:
Original description:
The purpose of this patch is to split off the case when a device does
not reply on the lower level (which is reported by HC hardware), and
a case when the device accepted the request, but does not reply at
upper level. This redefinition allows to diagnose issues easier,
without asking the user if the -110 happened "immediately".
The usbmon splits such cases already thanks to its timestamp, but
it's not always available.
I adjusted all drivers which I found affected (by searching for "urb").
Out of tree drivers may suffer a little bit, but I do not expect much
breakage. At worst they may print a few messages.
