Currently, the SourceControl will stay in power-down mode after resuming
from suspend. This patch resets the device after suspend to power it up.

Use the new usb-device pointer instead of back-casting when accessing
the struct usb_device when parsing endpoints.

Note that this introduces two lines that are longer than 80 chars on
purpose.

Add a new device quirk that can be used to blacklist endpoints.

Since commit 3e4f8e21c4f2 ("USB: core: fix check for duplicate

descriptor parsing.

In order to handle devices where the first interfaces with duplicate
endpoints are the ones that should have their endpoints ignored, we need
to add a blacklist.

<title>USB: hub: Don't record a connect-change event during reset-resume</title>

<id>8099f58f1ecddf4f374f4828a3dff8397c7cbd74</id>
<content type='text'>
Paul Zimmerman reports that his USB Bluetooth adapter sometimes
crashes following system resume, when it receives a
Get-Device-Descriptor request while it is busy doing something else.

Such a request was added by commit a4f55d8b8c14 ("usb: hub: Check
device descriptor before resusciation").  It gets sent when the hub
driver's work thread checks whether a connect-change event on an
enabled port really indicates a new device has been connected, as
opposed to an old device momentarily disconnecting and then
reconnecting (which can happen with xHCI host controllers, since they
automatically enable connected ports).

The same kind of thing occurs when a port's power session is lost
during system suspend.  When the system wakes up it sees a
connect-change event on the port, and if the child device's
persist_enabled flag was set then hub_activate() sets the device's
reset_resume flag as well as the port's bit in hub-&gt;change_bits.  The
reset-resume code then takes responsibility for checking that the same
device is still attached to the port, and it does this as part of the
device's resume pathway.  By the time the hub driver's work thread
starts up again, the device has already been fully reinitialized and
is busy doing its own thing.  There's no need for the work thread to
do the same check a second time, and in fact this unnecessary check is
what caused the problem that Paul observed.

Note that performing the unnecessary check is not actually a bug.
Devices are supposed to be able to send descriptors back to the host
even when they are busy doing something else.  The underlying cause of
Paul's problem lies in his Bluetooth adapter.  Nevertheless, we
shouldn't perform the same check twice in a row -- and as a nice side
benefit, removing the extra check allows the Bluetooth adapter to work
more reliably.

The work thread performs its check when it sees that the port's bit is
set in hub-&gt;change_bits.  In this situation that bit is interpreted as
though a connect-change event had occurred on the port _after_ the
reset-resume, which is not what actually happened.

One possible fix would be to make the reset-resume code clear the
port's bit in hub-&gt;change_bits.  But it seems simpler to just avoid
setting the bit during hub_activate() in the first place.  That's what
this patch does.

(Proving that the patch is correct when CONFIG_PM is disabled requires
a little thought.  In that setting hub_activate() will be called only
for initialization and resets, since there won't be any resumes or
reset-resumes.  During initialization and hub resets the hub doesn't
have any child devices, and so this code path never gets executed.)

Paul Zimmerman reports that his USB Bluetooth adapter sometimes
crashes following system resume, when it receives a
Get-Device-Descriptor request while it is busy doing something else.

Such a request was added by commit a4f55d8b8c14 ("usb: hub: Check
device descriptor before resusciation").  It gets sent when the hub
driver's work thread checks whether a connect-change event on an
enabled port really indicates a new device has been connected, as
opposed to an old device momentarily disconnecting and then
reconnecting (which can happen with xHCI host controllers, since they
automatically enable connected ports).

The same kind of thing occurs when a port's power session is lost
during system suspend.  When the system wakes up it sees a
connect-change event on the port, and if the child device's
persist_enabled flag was set then hub_activate() sets the device's
reset_resume flag as well as the port's bit in hub-&gt;change_bits.  The
reset-resume code then takes responsibility for checking that the same
device is still attached to the port, and it does this as part of the
device's resume pathway.  By the time the hub driver's work thread
starts up again, the device has already been fully reinitialized and
is busy doing its own thing.  There's no need for the work thread to
do the same check a second time, and in fact this unnecessary check is
what caused the problem that Paul observed.

Note that performing the unnecessary check is not actually a bug.
Devices are supposed to be able to send descriptors back to the host
even when they are busy doing something else.  The underlying cause of
Paul's problem lies in his Bluetooth adapter.  Nevertheless, we
shouldn't perform the same check twice in a row -- and as a nice side
benefit, removing the extra check allows the Bluetooth adapter to work
more reliably.

The work thread performs its check when it sees that the port's bit is
set in hub-&gt;change_bits.  In this situation that bit is interpreted as
though a connect-change event had occurred on the port _after_ the
reset-resume, which is not what actually happened.

One possible fix would be to make the reset-resume code clear the
port's bit in hub-&gt;change_bits.  But it seems simpler to just avoid
setting the bit during hub_activate() in the first place.  That's what
this patch does.

(Proving that the patch is correct when CONFIG_PM is disabled requires
a little thought.  In that setting hub_activate() will be called only
for initialization and resets, since there won't be any resumes or
reset-resumes.  During initialization and hub resets the hub doesn't
have any child devices, and so this code path never gets executed.)

<title>USB: hub: Fix the broken detection of USB3 device in SMSC hub</title>

Renesas R-Car H3ULCB + Kingfisher Infotainment Board is either not able
to detect the USB3.0 mass storage devices or is detecting those as
USB2.0 high speed devices.

The explanation given by Renesas is that, due to a HW issue, the XHCI
driver does not wake up after going to sleep on connecting a USB3.0
device.

In order to mitigate that, disable the auto-suspend feature
specifically for SMSC hubs from hub_probe() function, as a quirk.

Renesas Kingfisher Infotainment Board has two USB3.0 ports (CN2) which
are connected via USB5534B 4-port SuperSpeed/Hi-Speed, low-power,
configurable hub controller.

Pull USB/Thunderbolt/PHY driver updates from Greg KH:
 "Here is the big USB and Thunderbolt and PHY driver updates for
  5.6-rc1.

  With the advent of USB4, "Thunderbolt" has really become USB4, so the
  renaming of the Kconfig option and starting to share subsystem code
  has begun, hence both subsystems coming in through the same tree here.

  PHY driver updates also touched USB drivers, so that is coming in
  through here as well.

  Major stuff included in here are:
   - USB 4 initial support added (i.e. Thunderbolt)
   - musb driver updates
   - USB gadget driver updates
   - PHY driver updates
   - USB PHY driver updates
   - lots of USB serial stuff fixed up
   - USB typec updates
   - USB-IP fixes
   - lots of other smaller USB driver updates

  All of these have been in linux-next for a while now (the usb-serial
  tree is already tested in linux-next on its own before merged into
  here), with no reported issues"

[ Removed an incorrect compile test enablement for PHY_EXYNOS5250_SATA
  that causes configuration warnings    - Linus ]

<title>USB: usbfs: Always unlink URBs in reverse order</title>

When the kernel unlinks a bunch of URBs for a single endpoint, it
should always unlink them in reverse order.  This eliminates any
possibility that some URB x will be unlinked before it can execute but
the following URB x+1 will execute before it can be unlinked.  Such an
event would be bad, for obvious reasons.

Chris Dickens pointed out that usbfs doesn't behave this way when it
is unbound from an interface.  All pending URBs are cancelled, but in
the order of submission.  This patch changes the behavior to make the
unlinks occur in reverse order.  It similarly changes the behavior
when usbfs cancels the continuation URBs for a BULK endpoint.
