commit d86db25e53fa69e3e97f3b55dd82a70689787c5d upstream.

The DELAY_INIT quirk only reduces the frequency of enumeration failures
with the Logitech HD Pro C920 and C930e webcams, but does not quite
eliminate them. We have found that adding a delay of 100ms between the
first and second Get Configuration request makes the device enumerate
perfectly reliable even after several weeks of extensive testing. The
reasons for that are anyone's guess, but since the DELAY_INIT quirk
already delays enumeration by a whole second, wating for another 10th of
that isn't really a big deal for the one other device that uses it, and
it will resolve the problems with these webcams.

commit e0429362ab15c46ea4d64c3f8c9e0933e48a143a upstream.

We've encountered a rare issue when enumerating two Logitech webcams
after a reboot that doesn't power cycle the USB ports. They are spewing
random data (possibly some leftover UVC buffers) on the second
(full-sized) Get Configuration request of the enumeration phase. Since
the data is random this can potentially cause all kinds of odd behavior,
and since it occasionally happens multiple times (after the kernel
issues another reset due to the garbled configuration descriptor), it is
not always recoverable. Set the USB_DELAY_INIT quirk that seems to work
around the issue.

commit a1227f3c1030e96ebc51d677d2f636268845c5fb upstream.

ehci_irq() and ehci_hrtimer_func() can deadlock on ehci-&gt;lock when
threadirqs option is used. To prevent the deadlock use
spin_lock_irqsave() in ehci_irq().

This change can be reverted when hrtimer callbacks become threaded.

<title>USB: EHCI: add delay during suspend to prevent erroneous wakeups</title>

commit 3e8d6d85adedc59115a564c0a54b36e42087c4d9 upstream.

High-speed USB connections revert back to full-speed signalling when
the device goes into suspend.  This takes several milliseconds, and
during that time it's not possible to tell reliably whether the device
has been disconnected.

On some platforms, the Wake-On-Disconnect circuitry gets confused
during this intermediate state.  It generates a false wakeup signal,
which can prevent the controller from going to sleep.

To avoid this problem, this patch adds a 5-ms delay to the
ehci_bus_suspend() routine if any ports have to switch over to
full-speed signalling.  (Actually, the delay was already present for
devices using a particular kind of PHY power management; the patch
merely causes the delay to be used more widely.)

commit 823d12c95c666fa7ab7dad208d735f6bc6afabdc upstream.

People sometimes create their own custom-configured kernels and forget
to enable CONFIG_SCSI_MULTI_LUN.  This causes problems when they plug
in a USB storage device (such as a card reader) with more than one
LUN.

Fortunately, we can tell fairly easily when a storage device claims to
have more than one LUN.  When that happens, this patch asks the SCSI
layer to probe all the LUNs automatically, regardless of the config
setting.

The patch also updates the Kconfig help text for usb-storage,
explaining that CONFIG_SCSI_MULTI_LUN may be necessary.
