USB: altsetting overrides for usbtest

The usbtest driver includes some rather simple-minded logic for
selecting an altsetting to test.  It doesn't work well for the g_zero
gadget, because it selects altsetting 0 (which doesn't have
isochronous endpoints) rather than altsetting 1 (which does have them,
if the gadget's hardware supports them).  This prevents usbtest's
isochronous tests (15, 16, 22, and 23) from working with g_zero.

Since g_zero is one of the most common gadget drivers used for USB
testing, usbtest should do a better job of supporting it.  But since
some programs may rely on the current scheme for selecting
altsettings, I didn't want to change it.

Instead, this patch (as1655) adds a module parameter to usbtest, which
can be used to override the default altsetting.  Since usbtest is
never used by normal users (most distributions probably don't even
build it), the new module parameter won't inconvenience anybody.  In
any case, it is entirely optional -- leaving it unset preserves the
existing behavior.

The patch also fixes a related bug in usbtest: After selecting an
altsetting, the driver neglects to store its selection.

USB: EHCI: fix timer bug affecting port resume

This patch (as1652) fixes a long-standing bug in ehci-hcd.  The driver
relies on status polls to know when to stop port-resume signalling.
It uses the root-hub status timer to schedule these status polls.  But
when the driver for the root hub is resumed, the timer is rescheduled
to go off immediately -- before the port is ready.  When this happens
the timer does not get re-enabled, which prevents the port resume from
finishing until some other event occurs.

The symptom is that when a new device is plugged in, it doesn't get
recognized or enumerated until lsusb is run or something else happens.

The solution is to re-enable the root-hub status timer after every
status poll while a port resume is in progress.

This bug hasn't surfaced before now because we never used to try to
suspend the root hub in the middle of a port resume (except by
coincidence).

USB: EHCI: unlink one async QH at a time

This patch (as1648) fixes a regression affecting nVidia EHCI
controllers.  Evidently they don't like to have more than one async QH
unlinked at a time.  I can't imagine how they manage to mess it up,
but at least one of them does.

The patch changes the async unlink logic in two ways:

Each time an IAA cycle is started, only the first QH on the
async unlink list is handled (rather than all of them).

Async QHs do not all get unlinked as soon as they have been
empty for long enough.  Instead, only the last one (i.e., the
one that has been on the schedule the longest) is unlinked,
and then only if no other unlinks are in progress at the time.

This means that when multiple QHs are empty, they won't be unlinked as
quickly as before.  That's okay; it won't affect correct operation of
the driver or add an excessive load.  Multiple unlinks tend to be
relatively rare in any case.

USB: EHCI: remove ASS/PSS polling timeout

This patch (as1647) attempts to work around a problem that seems to
affect some nVidia EHCI controllers.  They sometimes take a very long
time to turn off their async or periodic schedules.  I don't know if
this is a result of other problems, but in any case it seems wise not
to depend on schedule enables or disables taking effect in any
specific length of time.

The patch removes the existing 20-ms timeout for enabling and
disabling the schedules.  The driver will now continue to poll the
schedule state at 1-ms intervals until the controller finally decides
to obey the most recent command issued by the driver.  Just in case
this hides a problem, a debugging message will be logged if the
controller takes longer than 20 polls.

I don't know if this will actually fix anything, but it can't hurt.

Those have been deprecated for a long time and
previous patches just converted all remaining

every piece of code related to those calls.
