commit afad19648f70c6493193e0a774bd754b7790b4a0 upstream.
I have added the ProductID=0xe729 VendorID=FTDI_VID=0x0403 which will
enable support for the Segway Robotic Mobility Platform (RMP200) in the
ftdi_sio kernel module. Currently, users of the Segway RMP200 must use
a RUN+="/sbin/modprobe -q ftdi-sio product=0xe729 vendor=0x0403 in a
udev rule to get the ftdi_sio module to handle the usb interface and
mount it on /dev/ttyXXX. This is not a good solution because some users
will have multiple USB to Serial converters which will use the ftdi_sio
module.

commit 33d973ad88ceb83ed1449592b7574b5b5bb33ac6 upstream.
Enlarging the buffer size via the MON_IOCT_RING_SIZE ioctl causes
general protection faults. It appears the culprit is an incorrect
argument to mon_free_buff: instead of passing the size of the current
buffer being freed, the size of the new buffer is passed.
Use the correct size argument to mon_free_buff when changing the size of
the buffer.

commit 47f19c0eedb377ad1ee8114f464d001ec5f96a69 upstream.
When an attempt is made to read the interface strings of the Artisman
Watchdog USB dongle (idVendor:idProduct 04b4:0526) an error is written
to the dmesg log (uhci_result_common: failed with status 440000) and the
dongle resets itself, resulting in a disconnect/reconnect loop.
Adding the dongle to the list of devices in quirks.c, with the same
quirk Alan Stern's previous patch for the Saitek Cyborg Gold 3D
joystick, stops the device from resetting and allows it to be used with
no problems.

commit 48826626263d4a61d06fd8c5805da31f925aefa0 upstream.
This patch (as1403) is a partial reversion of an earlier change
(commit 5f677f1d45b2bf08085bbba7394392dfa586fa8e "USB: fix remote
wakeup settings during system sleep"). After hearing from a user, I
realized that remote wakeup should be enabled during system sleep
whenever userspace allows it, and not only if a driver requests it
too.
Indeed, there could be a device with no driver, that does nothing but
generate a wakeup request when the user presses a button. Such a
device should be allowed to do its job.
The problem fixed by the earlier patch -- device generating a wakeup
request for no reason, causing system suspend to abort -- was also
addressed by a later patch ("USB: don't enable remote wakeup by
default", accepted but not yet merged into mainline). The device
won't be able to generate the bogus wakeup requests because it will be
disabled for remote wakeup by default. Hence this reversion will not
re-introduce any old problems.

commit c2572b78aa0447244a38e555ebb1b3b48a0088a5 upstream.
This patch fixes resource reclaim in error path of acm_probe:
1. In the case of "out of memory (read urbs usb_alloc_urb)\n")", there
is no need to call acm_read_buffers_free(acm) here. Fix it by goto
alloc_fail6 instead of alloc_fail7.
2. In the case of "out of memory (write urbs usb_alloc_urb)",
usb_alloc_urb may fail in any iteration of the for loop. Current
implementation does not properly free allocated snd->urb. Fix it by
goto alloc_fail8 instead of alloc_fail7.
3. In the case of device_create_file(&intf->dev,&dev_attr_iCountryCodeRelDate)
fail, acm->country_codes is kfreed. As a result, device_remove_file
for dev_attr_wCountryCodes will not be executed in acm_disconnect.
Fix it by calling device_remove_file for dev_attr_wCountryCodes
before goto skip_countries.

commit 6a1a82df91fa0eb1cc76069a9efe5714d087eccd upstream.
Call set_mctrl() and clear_mctrl() according to the flow control mode
selected. This makes serial communication for FT232 connected devices
work when CRTSCTS is not set.
This fixes a regression introduced by 4175f3e31 ("tty_port: If we are
opened non blocking we still need to raise the carrier"). This patch
calls the low-level driver's dtr_rts() function which consequently sets
TIOCM_DTR | TIOCM_RTS. A later call to set_termios() without CRTSCTS in
cflags, however, does not reset these bits, and so data is not actually
sent out on the serial wire.

commit 44ebd037c54f80db3121ac9f5fe6e677b76e11d5 upstream.
The length of the scatter gather list a driver can enqueue is limited by
the bus' sg_tablesize to 62 entries. Each entry will be described by at
least one transfer request block (TRB). If the entry's buffer crosses a
64KB boundary, then that entry will have to be described by two or more
TRBs. So even if the USB device driver respects sg_tablesize, the whole
scatter list may take more than 62 TRBs to describe, and won't fit on
the ring.
Don't assume that an empty ring means there is enough room on the
transfer ring. The old code would unconditionally queue this too-large
transfer, and over write the beginning of the transfer. This would mean
the cycle bit was unchanged in those overwritten transfers, causing the
hardware to think it didn't own the TRBs, and the host would seem to
hang.
Now drivers may see submit_urb() fail with -ENOMEM if the transfers are
too big to fit on the ring.

commit 1624ae1c19e227096ba85bfc389d9b99cb6f7dde upstream.
When the USB core installs a new interface, it unconditionally clears the
halts on all the endpoints on the new interface. Usually the xHCI host
needs to know when an endpoint is reset, so it can change its internal
endpoint state. In this case, it doesn't care, because the endpoints were
never halted in the first place.
To avoid issuing a redundant Reset Endpoint command, the xHCI driver looks
at xhci_virt_ep->stopped_td to determine if the endpoint was actually
halted. However, the functions that handle the stall never set that
variable to NULL after it dealt with the stall. So if an endpoint stalled
and a Reset Endpoint command completed, and then the class driver tried to
install a new alternate setting, the xHCI driver would access the old
xhci_virt_ep->stopped_td pointer. A similar problem occurs if the
endpoint has been stopped to cancel a transfer.

commit 9238f25d5d32a435277eb234ec82bacdd5daed41 upstream.
For periodic endpoints, we must let the xHCI hardware know the maximum
payload an endpoint can transfer in one service interval. The xHCI
specification refers to this as the Maximum Endpoint Service Interval Time
Payload (Max ESIT Payload). This is used by the hardware for bandwidth
management and scheduling of packets.
For SuperSpeed endpoints, the maximum is calculated by multiplying the max
packet size by the number of bursts and the number of opportunities to
transfer within a service interval (the Mult field of the SuperSpeed
Endpoint companion descriptor). Devices advertise this in the
wBytesPerInterval field of their SuperSpeed Endpoint Companion Descriptor.
For high speed devices, this is taken by multiplying the max packet size by the
"number of additional transaction opportunities per microframe" (the high
bits of the wMaxPacketSize field in the endpoint descriptor).
For FS/LS devices, this is just the max packet size.
The other thing we must set in the endpoint context is the Average TRB
Length. This is supposed to be the average of the total bytes in the
transfer descriptor (TD), divided by the number of transfer request blocks
(TRBs) it takes to describe the TD. This gives the host controller an
indication of whether the driver will be enqueuing a scatter gather list
with many entries comprised of small buffers, or one contiguous buffer.
It also takes into account the number of extra TRBs you need for every TD.
This includes No-op TRBs and Link TRBs used to link ring segments
together. Some drivers may choose to chain an Event Data TRB on the end
of every TD, thus increasing the average number of TRBs per TD. The Linux
xHCI driver does not use Event Data TRBs.
In theory, if there was an API to allow drivers to state what their
bandwidth requirements are, we could set this field accurately. For now,
we set it to the same number as the Max ESIT payload.
The Average TRB Length should also be set for bulk and control endpoints,
but I have no idea how to guess what it should be.

commit 1cf62246c0e394021e494e0a8f1013e80db1a1a9 upstream.
A SuperSpeed interrupt or isochronous endpoint can define the number of
"burst transactions" it can handle in a service interval. This is
indicated by the "Mult" bits in the bmAttributes of the SuperSpeed
Endpoint Companion Descriptor. For example, if it has a max packet size
of 1024, a max burst of 11, and a mult of 3, the host may send 33
1024-byte packets in one service interval.
We must tell the xHCI host controller the number of multiple service
opportunities (mults) the device can handle when the endpoint is
installed. We do that by setting the Mult field of the Endpoint Context
before a configure endpoint command is sent down. The Mult field is
invalid for control or bulk SuperSpeed endpoints.

This is a backport of commit 5f677f1d45b2bf08085bbba7394392dfa586fa8e.
Some of the functionality had to be removed, but it should still fix
the webcam problem.
This patch (as1363b) changes the way USB remote wakeup is handled
during system sleeps. It won't be enabled unless an interface driver
specifically needs it. Also, it won't be enabled during the FREEZE or
QUIESCE phases of hibernation, when the system doesn't respond to
wakeup events anyway.
This will fix problems people have reported with certain USB webcams
that generate wakeup requests when they shouldn't, and as a result
cause system suspends to fail. See
