The original code was passing a stack variable as a dma buffer, so I
made it an allocated variable.  Instead of adding a bunch of kfree()
calls, I changed all the error return paths to gotos.

Also I noticed that the error checking wasn't correct because
usb_get_descriptor() can return negative values.

While I was at it, I made an unrelated white space change by moving
the unicode_to_ascii() on to one line.

Return values are being initialised to zero only to be unconditionally
assigned to a few instructions later. This may give the impression that
zero is returned on success, which is not the case.

I've got a crappy cypress converter here, and while running at higher
baud rates craps out on throughput, it works fine with lower ones.
While it'd be nice to simply use a lower baud rate, not all devices
can be configured this way, and it is possible to (slowly) interact
at higher rates by sending a byte at a time.  So let people force
higher rates when they need it via a module parameter.

This patch adds support for Dell Computer Corp. Wireless 5720 VZW Mobile
Broadband (EVDO Rev-A) Minicard GPS Port.  I stole the name from lsusb,
but my card does not have a GPS on it (at least not that I can make
function). I'm sure the patch is whitespace damaged but the one line
addition should be fairly straightforward nonetheless.

- add FTDI device IDs for several ELV devices and NXTCam of Lego Mindstorms NXT
- add hopefully helpful new_id comment
- remove less helpful "Due to many user requests for multiple ELV devices we enable
  them by default." comment (we simply add _all_ known devices - an
  enduser shouldn't have to fiddle with obscure module parameters...).
- add myself to DRIVER_AUTHOR

added new device pid (PAPOUCH_AD4USB_PID) to ftdi_sio.h and ftdi_sio.c

AD4USB measuring converter is a 4-input A/D converter which enables the
user to measure to four current inputs ranging from 0(4) to 20 mA or
voltage between 0 and 10 V. The measured values are then transferred to
a superior system in digital form. The AD4USB communicates via USB.
Powered is also via USB.  datasheet in english is here:

This is a (almost) sort-only patch to sort FTDI device
product ID definitions in new ftdi_sio_ids.h header.

Advantage is that new device ID submissions will now have a specific (sorted)
position - less future merge conflicts.

Minor checkpatch.pl warnings were eliminated whereever it made sense,
very minor text changes.

This is a strictly move-only patch to relocate all FTDI device
product ID definitions to their own ftdi_sio_ids.h header
(following the usual *_ids.h kernel tree convention, too),
thus correcting the slightly too messy appearance
(crucial driver defines were stuck somewhere in the decaying middle swamp
of the huge existing header).
