112225b13c USB: sierra: Add TRU-Install (c) Support
This patch adds compatibility with Sierra Wireless' new TRU-Install
feature. Future devices that use this feature will not work unless this
patch has been applied.

9e85c5f632 USB: sierra: cleanup the startup and shutdown path
This removes the ugly code that was copied from the keyspan driver and
allocates the in urbs in a much shorter code path that can be understood
easier.

Also turned off the interrupt urb when no port was open as it's not nice
to keep the bus busy for no good reason at all (this should be a power
savings.)

All in all, this saved over 40 lines of code and cleaned things up
better.

17c2327419 USB: sierra: remove incorrect usage of the urb status field
You can't rely on the fact that the status really is correct like it was.

Also simplified the write path and now we allocate the urb and data on
the fly, instead of trying to do that really odd timeout check which I
am guessing doesn't really work properly.  This should speed up the
device by keeping the hardware queue full easier.

As a benefit, this reduces the size of the driver.

17dd2215ad USB: serial: sierra: clean up urb->status usage
This done in anticipation of removal of urb->status, which will make
that patch easier to review and apply in the future.

5b7da8f6ff USB: Add support for Sierra Wireless Aircard 595U
This patch adds support for the newly released Aircard 595U EVDO
modem to the Sierra Wireless driver (sierra.c) in kernel 2.6.21.

I suspect that my mailer may be mangling patches so let me know and
I'll try to resend it.

ebcf3ede6d USB: sierra close race
the sierra driver does not directly use usb_kill_urb(). It uses a wrapper.
This wrapper means that callbacks which are running are not killed during
close, resubmitting and illicitly pushing data into the tty layer.
The whole purpose of usb_kill_urb() is subverted. The wrapper must be removed.
The same problem as the option driver.

d9b1b78773 USB serial: add driver pointer to all usb-serial drivers
Every usb serial driver should have a pointer to the corresponding usb driver.
So the usb serial core can add a new id not only to the usb serial driver, but
also to the usb driver.

Also the usb drivers of ark3116, mos7720 and mos7840 missed the flag
no_dynamic_id=1. This is added now.

606d099cdd [PATCH] tty: switch to ktermios
This is the grungy swap all the occurrences in the right places patch that
goes with the updates.  At this point we have the same functionality as
before (except that sgttyb() returns speeds not zero) and are ready to
begin turning new stuff on providing nobody reports lots of bugs

If you are a tty driver author converting an out of tree driver the only
impact should be termios->ktermios name changes for the speed/property
setting functions from your upper layers.

If you are implementing your own TCGETS function before then your driver
was broken already and its about to get a whole lot more painful for you so
please fix it 8)

Also fill in c_ispeed/ospeed on init for most devices, although the current
code will do this for you anyway but I'd like eventually to lose that extra
paranoia

033a3fb980 USB: Sierra Wireless driver update
The largest feature in this patch is that it adds significant throughput
increase to the Sierra driver and adds support for modem status line
control (e.g. the DTR line). This patch also updates the current sierra.c
driver so that it supports both 3-port Sierra devices and 1-port legacy
devices and removes Sierra's references in other related files (Kconfig and
airprime.c).
