Here are the USB-serial updates for 4.15-rc1, including:
 
  - three fixes for longstanding issues in garmin_gps and metro-usb which
    could lead to NULL-pointer dereferences and memory leaks
 
  - a workaround for broken f81534 firmware-handling of overruns
 
  - f81534 break support, and
 
  - conversion to timer_setup()
 
 Included are also various clean ups and a new qcserial device id.
 
 All have been in linux-next with no reported issues.

Ji-Ze Hong (Peter Hong) dea744bae7 USB: serial: f81534: fix hang-up on overrun
The F81532/534 without this patch will hang-up on data overrun.

It's caused by enable LSR interrupt in IER by default and occur data
overrun, the chip will busy for process LSR interrupt but not read LSR
internally. It will not responed for USB control endpoint0 and we can't
read LSR from driver in this situration.

So we'll disable the LSR interrupt in probe() and submit the LSR worker to
clear LSR state when reported LSR error bit with bulk-in data in
f81534_process_per_serial_block().

Johan Hovold 2944fd27d1 USB: serial: drop unused core USB driver
Drop the usb-serial-core USB driver that was registered at module init
but then never used.

This was a remnant dating back to 2004 (!) when this struct usb_driver
was used for the generic driver; see commit bbc53b7d7322 ("USB: fix bug
where removing usb-serial modules or usb serial devices could oops") in
the tglx bitkeeper-history archive.

Note that every usb-serial driver (including the generic one) registers
its own USB (interface) driver along with its usb-serial bus drivers.

Johan Hovold ee13a25fc3 USB: serial: metro-usb: add missing interrupt-out endpoint check
One class of "unidirectional" devices managed by this driver uses an
interrupt-out endpoint to send control messages at open and close. Due
to a missing endpoint sanity check, this could result in an interrupt
URB being submitted to endpoint 0 instead. This would be caught by
USB core (without a WARN dump), but let's verify that the expected
endpoints are present at probe rather than when a port is later opened.

Make sure to kill the interrupt-in URB after a failed open request.
Apart from saving power (and avoiding stale input after a later

When adding GPIO support for the cp2105, the mentioned commit by Martyn
Welch introduced a query for the part number of the chip. Unfortunately
the driver aborts probing when this query fails, so currently the driver
can not be used with chips not supporting this query.
I have a data cable for Siemens mobile phones (ID 10ab:10c5) where this
is the case.
With this patch the driver can be bound even if the part number can not
be queried.

Johan Hovold 83c9a2d1a6 USB: serial: ftdi_sio: remove broken alt-speed handling
Remove the broken alt_speed code, and warn when trying to set the line
speed using TIOCSSERIAL and SPD flags.

The use of SPD flags to set the line speed has been deprecated since
v2.1.69 and support for alt_speed (e.g. "warp") has even been removed
from TTY core in v3.10 by commit 6865ff222c ("TTY: do not warn about
setting speed via SPD_*"), effectively breaking all driver
implementations of this except for serial core.

Also remove the verbose and outdated comment on how to set baud rates.

Note that setting a custom divisor will continue to work with the
caveat that 38400 must again be selected every time the divisor is
changed since v2.6.24 and commit 669a6db103 ("USB: ftd_sio: cleanups
and updates for new termios work") which started reporting back the
actual baud rate used.

Magnus Lynch 08f741a933 USB: serial: qcserial: expose methods for modem control
The qcserial driver fails to expose the .tiocmget and .tiocmset methods
available from usb_wwan. These methods are required by ioctl commands
dealing with the modem control signals DTR, RTS, etc.

With these methods not set ioctl calls intended to control the DTR state
will fail. For example, pppd drops and raises DTR in preparation to
dialing the modem, which handles the case of the modem already being
connected by making it hang up and return to command mode. DTR control
being unavailable will lead to a protracted failure to connect as the
modem will be stuck in a state not responsive to command.

I have tested that with this patch the described case is handled
successfully. There is an analogous method for .ioctl available from
usb_wwan (as used in option.c) but I conservatively omitted that for
lack of familiarity.

This patch adds support for recognition of ARM-USB-TINY(H) devices which

By suggestion from Johan Hovold it is possible to replace
ftdi_jtag_quirk with a bit more generic construction. Since all
Olimex-ARM debuggers has exactly two ports, we could safely always use
only second port within the debugger family.

Commit 557aaa7ffa ("ft232: support the ASYNC_LOW_LATENCY
flag") enables unprivileged users to set the FTDI latency timer,
but there was a logic flaw that skipped sending the corresponding
USB control message to the device.

Specifically, the device latency timer would not be updated until next
open, something which was later also inadvertently broken by commit
c19db4c9e4 ("USB: ftdi_sio: set device latency timeout at port
probe").

A recent commit c6dce26266 ("USB: serial: ftdi_sio: fix extreme
low-latency setting") disabled the low-latency mode by default so we now
need this fix to allow unprivileged users to again enable it.

Here is the big USB patchset for 4.12-rc1.
 
 Lots of good stuff here, after many many many attempts, the kernel
 finally has a working typeC interface, many thanks to the Heikki and
 Guenter and others who have taken the time to get this merged.  It
 wasn't an easy path for them at all.
 
 There's also a staging driver that uses this new api, which is why it's
 coming in through this tree.
 
 Along with that, there's the usual huge number of changes for gadget
 drivers, xhci, and other stuff.  Johan also finally refactored pretty
 much every driver that was looking at USB endpoints to do it in a common
 way, which will help prevent any "badly-formed" devices from causing
 problems in drivers.  That too wasn't a simple task.
 
 All of these have been in linux-next for a while with no reported
 issues.
