When system is being suspended, if host device is not allowed to do wakeup,
xhci_suspend() needs to clear all root port wake on bits. Otherwise, some
platforms may generate spurious wakeup, even if PCI PME# is disabled.
The initial commit ff8cbf250b44 ("xhci: clear root port wake on bits"),
which also got into stable, turned out to not work correctly and had to
be reverted, and is now rewritten.

If a device is halted and reuturns a STALL, then the halted endpoint
needs to be cleared both on the host and device side. The host
side halt is cleared by issueing a xhci reset endpoint command. The device side
is cleared with a ClearFeature(ENDPOINT_HALT) request, which should
be issued by the device driver if a URB reruen -EPIPE.
Previously we cleared the host side halt after the device side was cleared.
To make sure the host side halt is cleared in time we want to issue the
reset endpoint command immedialtely when a STALL status is encountered.
Otherwise we end up not following the specs and not returning -EPIPE
several times in a row when trying to transfer data to a halted endpoint.

A halted endpoint ring must first be reset, then move the ring
dequeue pointer past the problematic TRB. If we start the ring too
early after reset, but before moving the dequeue pointer we
will end up executing the same problematic TRB again.
As we always issue a set transfer dequeue command after a reset
endpoint command we can skip starting endpoint rings at reset endpoint
command completion.
Without this fix we end up trying to handle the same faulty TD for
contol endpoints. causing timeout, and failing testusb ctrl_out write
tests.

commit 6856d30 (usb: dwc3: ep0: return early
on NULL requests) tried to fix a minor corner
case where we could dereference a NULL pointer
but it also ended up introducing some dead code.
Unfortunately, that dead code, if reached, could
end up starving the endpoint request list because
a request would never be given back when it should.
Fix this by moving the check for empty request list
before its first use.

Add new quirk for devices that cannot handle control-line state
requests.
Note that we currently send these requests to all devices, regardless of
whether they claim to support it, but that errors are only logged if
support is claimed.
Since commit 0943d8ead30e ("USB: cdc-acm: use tty-port dtr_rts"), which
only changed the timings for these requests slightly, this has been
reported to cause occasional firmware crashes on Simtec Electronics
Entropy Key devices after re-enumeration. Enable the quirk for this
device.

It is safe to call notify disconnect when the usb core
thinks the device is disconnected.
This commit also fixes one bug found at below situation:
we have not enabled usb wakeup, we do system suspend when
there is an usb device at the port, after suspend, we plug out
the usb device, then plug in device again. At that time,
the nofity disconnect was not called at current code, as
the controller doesn't know the usb device was disconnected
during the suspend, but USB core knows the port has changed
during that periods.
So to fix this problem, and let the usb core call notify disconnect.

(port_dev->child, the child device at roothub is not NULL), we

This fixes a bug that do fast plug in/out test, and the notify_disconnect
is not called due to roothub child is NULL and the enumeration has failed.

Streams seem to be broken on the Asmedia 1042. An uas capable Seagate disk
which is known to work fine with other controllers causes the system to freeze
when connected over usb-3 with this controller, where as it works fine with
uas in usb-2 ports, indicating a problem with streams.
This is a bit bigger hammer then I would like to use for this, but for now it
will have to make do. I've ordered a pci-e usb controller card with an Asmedia
1042, once that arrives I'll try to get streams to work (with a quirk flag if
necessary) and then we can re-enable them. For now this at least makes uas
capable disk enclosures work again by forcing fallback to the usb-storage
driver.

Sometimes mass-storage devices using the Bulk-only transport will
mistakenly skip the data phase of a command. Rather than sending the
data expected by the host or sending a zero-length packet, they go
directly to the status phase and send the CSW.
This causes problems for usb-storage, for obvious reasons. The driver
will interpret the CSW as a short data transfer and will wait to
receive a CSW. The device won't have anything left to send, so the
command eventually times out.
The SCSI layer doesn't retry commands after they time out (this is a
relatively recent change). Therefore we should do our best to detect
a skipped data phase and handle it promptly.
This patch adds code to do that. If usb-storage receives a short
13-byte data transfer from the device, and if the first four bytes of
the data match the CSW signature, the driver will set the residue to
the full transfer length and interpret the data as a CSW.
This fixes Bugzilla #86611.
