[ Upstream commit 9933698f6119886c110750e67c10ac66f12b730f ]

Due to (wIndex &amp; 0xff) - 1 can get an integer greater than 15, this
can cause array index to be out of bounds since the size of array
port_status is 15. This change prevents a possible out-of-bounds
pointer computation by forcing the use of a valid port number.

<title>xhci: Fresco FL1100 controller should not have BROKEN_MSI quirk set.</title>

<content type='text'>
The Fresco Logic FL1100 controller needs the TRUST_TX_LENGTH quirk like
other Fresco controllers, but should not have the BROKEN_MSI quirks set.

BROKEN_MSI quirk causes issues in detecting usb drives connected to docks
with this FL1100 controller.
The BROKEN_MSI flag was apparently accidentally set together with the
TRUST_TX_LENGTH quirk

Original patch went to stable so this should go there as well.

Make xhci_disable_slot() synchronous, thus ensuring it, and
xhci_free_dev() calling it return after xHC controller completes
the disable slot command.

Otherwise the roothub and xHC host may runtime suspend, and clear the
command ring while the disable slot command is being processed.

This causes a command completion mismatch as the completion event can't
be mapped to the correct command.
Command ring gets out of sync and commands time out.
Driver finally assumes host is unresponsive and bails out.

When the xHCI is quirked with XHCI_RESET_ON_RESUME, runtime resume
routine also resets the controller.

This is bad for USB drivers without reset_resume callback, because
there's no subsequent call of usb_dev_complete() -&gt;
usb_resume_complete() to force rebinding the driver to the device. For
instance, btusb device stops working after xHCI controller is runtime
resumed, if the controlled is quirked with XHCI_RESET_ON_RESUME.

So always take XHCI_RESET_ON_RESUME into account to solve the issue.

<title>xhci: Fix commad ring abort, write all 64 bits to CRCR register.</title>

<id>09f736aa95476631227d2dc0e6b9aeee1ad7ed58</id>
<content type='text'>
Turns out some xHC controllers require all 64 bits in the CRCR register
to be written to execute a command abort.

The lower 32 bits containing the command abort bit is written first.
In case the command ring stops before we write the upper 32 bits then
hardware may use these upper bits to set the commnd ring dequeue pointer.

Solve this by making sure the upper 32 bits contain a valid command
ring dequeue pointer.

The original patch that only wrote the first 32 to stop the ring went
to stable, so this fix should go there as well.

  These include:

   - two reverts of xhci and USB core patches that are causing problems
     in many systems.

   - xhci 3.1 enumeration delay fix for systems that were having
     problems.

  All three of these have been in linux-next all week with no reported

Pull USB fixes from Greg KH:
 "Here are some small reverts and fixes for USB drivers for issues that
  came up during the 5.16-rc1 merge window.

  These include:

   - two reverts of xhci and USB core patches that are causing problems
     in many systems.

   - xhci 3.1 enumeration delay fix for systems that were having
     problems.

  All three of these have been in linux-next all week with no reported
  issues"
