commit 45f750c16cae3625014c14c77bd9005eda975d35 upstream.

The code to prevent a bus suspend if a USB3 port was still in link training
also reacted to USB2 port polling state.
This caused bus suspend to busyloop in some cases.
USB2 polling state is different from USB3, and should not prevent bus
suspend.

Limit the USB3 link training state check to USB3 root hub ports only.
The origial commit went to stable so this need to be applied there as well

commit d57ec3c83b5153217a70b561d4fb6ed96f2f7a25 upstream.

The HP lt4132 is a rebranded Huawei ME906s-158 LTE modem.

The interface with protocol 0x16 is "CDC ECM &amp; NCM" according to the *.inf
files included with the Windows driver. Attaching the option driver to it
doesn't result in a /dev/ttyUSB* device being created, so I've excluded it.
Note that it is also excluded for corresponding Huawei-branded devices, cf.
commit d544db293a44 ("USB: support new huawei devices in option.c").

<title>xhci: Prevent U1/U2 link pm states if exit latency is too long</title>

commit 0472bf06c6fd33c1a18aaead4c8f91e5a03d8d7b upstream.

Don't allow USB3 U1 or U2 if the latency to wake up from the U-state
reaches the service interval for a periodic endpoint.

This is according to xhci 1.1 specification section 4.23.5.2 extra note:

"Software shall ensure that a device is prevented from entering a U-state
 where its worst case exit latency approaches the ESIT."

Allowing too long exit latencies for periodic endpoint confuses xHC
internal scheduling, and new devices may fail to enumerate with a
"Not enough bandwidth for new device state" error from the host.

<title>xhci: workaround CSS timeout on AMD SNPS 3.0 xHC</title>

commit a7d57abcc8a5bdeb53bbf8e87558e8e0a2c2a29d upstream.

Occasionally AMD SNPS 3.0 xHC does not respond to
CSS when set, also it does not flag anything on SRE and HCE
to point the internal xHC errors on USBSTS register. This stalls
the entire system wide suspend and there is no point in stalling
just because of xHC CSS is not responding.

To work around this problem, if the xHC does not flag
anything on SRE and HCE, we can skip the CSS
timeout and allow the system to continue the suspend. Once the
system resume happens we can internally reset the controller
using XHCI_RESET_ON_RESUME quirk

commit 704620afc70cf47abb9d6a1a57f3825d2bca49cf upstream.

When reading an extra descriptor, we need to properly check the minimum
and maximum size allowed, to prevent from invalid data being sent by a
device.

commit 704620afc70cf47abb9d6a1a57f3825d2bca49cf upstream.

When reading an extra descriptor, we need to properly check the minimum
and maximum size allowed, to prevent from invalid data being sent by a
device.

commit 2f2dde6ba89b1ef1fe23c1138131b315d9aa4019 upstream.

Some lower volume SanDisk Ultra Flair in 16GB, which the VID:PID is
in 0781:5591, will aggressively request LPM of U1/U2 during runtime,
when using this thumb drive as the OS installation key we found the
device will generate failure during U1 exit path making it dropped
from the USB bus, this causes a corrupted installation in system at
the end.

i.e.,
[  166.918296] hub 2-0:1.0: state 7 ports 7 chg 0000 evt 0004
[  166.918327] usb usb2-port2: link state change
[  166.918337] usb usb2-port2: do warm reset
[  166.970039] usb usb2-port2: not warm reset yet, waiting 50ms
[  167.022040] usb usb2-port2: not warm reset yet, waiting 200ms
[  167.276043] usb usb2-port2: status 02c0, change 0041, 5.0 Gb/s
[  167.276050] usb 2-2: USB disconnect, device number 2
[  167.276058] usb 2-2: unregistering device
[  167.276060] usb 2-2: unregistering interface 2-2:1.0
[  167.276170] xhci_hcd 0000:00:15.0: shutdown urb ffffa3c7cc695cc0 ep1in-bulk
[  167.284055] sd 0:0:0:0: [sda] tag#0 FAILED Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK
[  167.284064] sd 0:0:0:0: [sda] tag#0 CDB: Read(10) 28 00 00 33 04 90 00 01 00 00
...

Analyzed the USB trace in the link layer we realized it is because
of the 6-ms timer of tRecoveryConfigurationTimeout which documented
on the USB 3.2 Revision 1.0, the section 7.5.10.4.2 of "Exit from
Recovery.Configuration"; device initiates U1 exit -&gt; Recovery.Active
-&gt; Recovery.Configuration, then the host timer timeout makes the link
transits to eSS.Inactive -&gt; Rx.Detect follows by a Warm Reset.

Interestingly, the other higher volume of SanDisk Ultra Flair sharing
the same VID:PID, such as 64GB, would not request LPM during runtime,
it sticks at U0 always, thus disabling LPM does not affect those thumb
drives at all.

The same odd occures in SanDisk Ultra Fit 16GB, VID:PID in 0781:5583.

commit effd14f66cc1ef6701a19c5a56e39c35f4d395a5 upstream.

Cherry G230 Stream 2.0 (G85-231) and 3.0 (G85-232) need this quirk to
function correctly. This fixes a but where double pressing numlock locks
up the device completely with need to replug the keyboard.
