commit 5bc38d33a5a1209fd4de65101d1ae8255ea12c6e upstream.
In some cases, driver trees to send Status Stage twice.
The first one from upper layer of gadget usb subsystem and
second time from controller driver.
This patch fixes this issue and remove tricky handling of
SET_INTERFACE from controller driver which is no longer
needed.

commit 1272fd652a226ccb34e9f47371b6121948048438 upstream.
PCI based platform can have more than two PCI functions.
USBSS PCI Glue driver during initialization should
consider only DRD/HOST/DEVICE PCI functions and
all other should be ignored. This patch adds additional
condition which causes that only DRD and HOST/DEVICE
function will be accepted.

commit 1301c7b9f7efad2f11ef924e317c18ebd714fc9a upstream.
After doorbell DMA fetches the TRB. If during dequeuing request
driver changes NORMAL TRB to LINK TRB but doesn't delete it from
controller cache then controller will handle cached TRB and packet
can be lost.
The example scenario for this issue looks like:
1. queue request - set doorbell
2. dequeue request
3. send OUT data packet from host
4. Device will accept this packet which is unexpected
5. queue new request - set doorbell
6. Device lost the expected packet.
By setting DFLUSH controller clears DRDY bit and stop DMA transfer.

commit ae423ef5d095e09970f52c08020fdbf7f9d87c22 upstream.
Patch implements the handling of ZLP for control transfer.
To send the ZLP driver must prepare the extra TRB in TD with
length set to zero and TRB type to TRB_NORMAL.
The first TRB must have set TRB_CHAIN flag, TD_SIZE = 1
and TRB type to TRB_DATA.

commit 9d5333c931347005352d5b8beaa43528c94cfc9c upstream.
When usb 3.0 hub connect with one USB 2.0 device and NO USB 3.0 device,
some usb hub reports endless port reset message.

[ 192.504977] hub 2-1:1.0: 4 ports detected
[ 192.852066] usb 2-1: USB disconnect, device number 89
The reason is the runtime pm state of USB2.0 port is active and
USB 3.0 port is suspend, so parent device is active state.
cat /sys/bus/platform/devices/5b110000.usb/5b130000.usb/xhci-hcd.1.auto/usb2/power/runtime_status

So xhci_cdns3_suspend_quirk() have not called. U3 configure is not applied.
move U3 configure into host start. Reinit again in resume function in case
controller power lost during suspend.

commit d5dcc33677d7415c5f23b3c052f9e80cbab9ea4e upstream.
The TRB_SMM flag indicates that DMA has completed the TD service with
this TRB. Usually it’s a last TRB in TD. In case of ISOC transfer for
bInterval > 1 each ISOC transfer contains more than one TD associated
with usb request (one TD per ITP). In such case the TRB_SMM flag will
be set in every TD and driver will recognize the end of transfer after
processing the first TD with TRB_SMM. In result driver stops updating
request->actual and returns incorrect actual length.
To fix this issue driver additionally must check TRB_CHAIN which is not
used for isochronous transfers.

This bug was found by a static analyzer. The analysis employs
differential checking to identify inconsistent security operations
(e.g., checks or kfrees) between two code paths and confirms that the
inconsistent operations are not recovered in the current function or
the callers, so they constitute bugs.
Note that, as a bug found by static analysis, it can be a false
positive or hard to trigger. Multiple researchers have cross-reviewed
the bug.
Builds with CONFIG_USB_CDNSP_GADGET=y show no new warnings,
and our static analyzer no longer warns about this code.

Merge tag 'usb-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB / Thunderbolt updates from Greg KH:
"Here is the big set of USB and Thunderbolt patches for 5.14-rc1.
Nothing major here just lots of little changes for new hardware and
features. Highlights are:
- more USB 4 support added to the thunderbolt core
- build warning fixes all over the place
- usb-serial driver updates and new device support
- mtu3 driver updates
- gadget driver updates
- dwc3 driver updates
- dwc2 driver updates
- isp1760 host driver updates
- musb driver updates
- lots of other tiny things.
Full details are in the shortlog.
All of these have been in linux-next for a while now with no reported
issues"

...
- Added option for per CPU threads to the hwlat tracer
- Have hwlat tracer handle hotplug CPUs
- New tracer: osnoise, that detects latency caused by interrupts, softirqs
and scheduling of other tasks.
- Added timerlat tracer that creates a thread and measures in detail what
sources of latency it has for wake ups.
- Removed the "success" field of the sched_wakeup trace event.
This has been hardcoded as "1" since 2015, no tooling should be looking
at it now. If one exists, we can revert this commit, fix that tool and
try to remove it again in the future.
- tgid mapping fixed to handle more than PID_MAX_DEFAULT pids/tgids.
- New boot command line option "tp_printk_stop", as tp_printk causes trace
events to write to console. When user space starts, this can easily live
lock the system. Having a boot option to stop just after boot up is
useful to prevent that from happening.
- Have ftrace_dump_on_oops boot command line option take numbers that match
the numbers shown in /proc/sys/kernel/ftrace_dump_on_oops.
- Bootconfig clean ups, fixes and enhancements.
- New ktest script that tests bootconfig options.
- Add tracepoint_probe_register_may_exist() to register a tracepoint
without triggering a WARN*() if it already exists. BPF has a path from
user space that can do this. All other paths are considered a bug.
- Small clean ups and fixes

The __assign_str macro has an unusual ending semicolon but the vast
majority of uses of the macro already have semicolon termination.
$ git grep -P '\b__assign_str\b' | wc -l
551
$ git grep -P '\b__assign_str\b.*;' | wc -l
480
Add semicolons to the __assign_str() uses without semicolon termination
and all the other uses without semicolon termination via additional defines
that are equivalent to __assign_str() with the eventual goal of removing
the semicolon from the __assign_str() macro definition.

must remove request from ep->pending_list.

while (!list_empty(&pep->pending_list)) {
preq = next_request(&pep->pending_list);
