- If a termios change fails due to lack of memory we should copy the
old settings back over as the device has not changed
- Note various locking problems
- kl5kusb105 had various remaining tty flag handling problems
- Make safe_serial use tty_insert_flip_string not open coded loops
- set termios speed properly in usb_serial

The usb-serial core no longer checks these fields so remove them from
all of the individual drivers. They will be removed from the usb-serial
core in a patch later in the series.

- Set the i/ospeed in the initial termios properly
- Use the tty_encode_baud_rate functions to report resulting rates properly

The Coverity checker spotted that we'd have already oops'ed if one of

o Don't parse the cflag for baud rates, its not valid to do so
any more and this driver got it wrong anyway
o Don't do clever termios change checks in drivers and get them
wrong (arguably we should do some smart ones in the tty core but
stty to change nothing is *not* a common or critical path
I don't have the hardware so if you can test this carefully please do. I
thought fixing it up this far was better than marking it and other bits of
USB serial && BROKEN

Fix debug output. Previously, it would output "0xFFFFFFB0" on 32-bit
archs (and probably "0xFFFFFFFFFFFFFFB0" on 64-bits), because buf is
taken as signed char, which is promoted to signed int, while %x always
expects an unsigned int.

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.

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

Add (dummy?) support for TIOCGSERIAL and TIOCSSERIAL ioctl calls to the USB
serial driver file `ark3116.c'. This is sufficient for me to run wvdial
successfully, receive my email, and do webbrowsing with firefox. On the
other hand, running the cvs program to update archives seems not to work,
and the traceroute command sometimes says
send failed: No buffer space available
Looks like a buffering problem... My knowledge of serial device drivers is
zero, so I can't fix this -- I just did a cut'n'paste from other USB serial
drivers...

USB serial outside of the kernel tree can not build properly due to
usb-serial.h being buried down in the source tree. This patch moves the
location of the file to include/linux/usb and fixes up all of the usb
serial drivers to handle the move properly.
