list_entry, which is an alias for container_of, cannot return NULL, as
there is no way to add a NULL value to a doubly linked list.
A simplified version of the semantic match that findds this problem is as
follows:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@r@
expression x,E;
statement S1,S2;
position p,p1;
@@
*x = list_entry@p(...)
... when != x = E
*if@p1 (x == NULL) S1 else S2
// </smpl>

According to FCC (*1) and *2 there's really RT2070L inside, but according
to *2 RT3070 and RT2070 are compatible.

This patch implements several improvements to the set_termios method
suggested by Alan Cox:
* Correct check for whether any changes are being requested.
* Inform callers that mark/space parity isn't supported by always
clearing the bit.
* Pass back the actual used baud rate in case it doesn't match what was
requested.
Remaining known issues are that IXANY flow control is not supported, but
we don't tell the caller that, and input and output XON/XOFF flow
control are either both on or both off, but we don't indicate that back
to the caller either.

This patch contains changes made in the course of successfully reading
data from the device. These consist of a number of corrections and
additions to debug messages, and a fix for incorrect calculation of the
number of characters in the device FIFO which affected the operation of
the write_room method.
The use of semaphores to control access to port settings is replaced by
the preferred use of mutexes as this is the only code that uses them.

Aug 18 17:09:32 [kernel] Fixing recursive fault but reboot is needed!
My guess is that my driver is doing something "wrong" in terms of it's
interface to the higher level layers and so is causing the oops. Are
there any mechanisms to turn on more checking / debugging in the layers
above the usb-serial layer to try and catch the cause of the problem?
I've already got USB_DEBUG enabled, what others might be relevant
(presumably USB_SERIAL_DEBUG isn't)?

This patch implements close(), read(), write() and some ioctls, and
fixes some implementation issues in open(). Compared to the previous
patch it doesn't suffer an oops in the module code, however if you try
to open any of the serial devices a second time then an oops occurs in
tty_open(), presumably because my code isn't playing nicely on the
previous close():

Read and Write also do not work at the moment, and I'm fairly sure that
the URB completion callbacks are not running. Why this is I don't know,
and haven't tried to investigate.

Part two of the driver implementation has finally got done. It
implements the rest of open and the callback for reads from the box. I
seem to have finally found a structure that can be made to work, with a
single set of URBs for bulk read and write for the whole device, which
are used by all the ports. I've rationalised a few things, but there
will still be a lot of clean-up needed.
This one definitely can panic the kernel when a port is opened for
reading, but I'm off on holiday so I thought I'd post where I have got
to so far. I haven't tried to debug why it panics with a null pointer
dereference yet.

The patch is of the "works as far as it goes" variety, in that the
module compiles and loads, the device nodes are registered and the unit
switched on, but nothing actually works. On the other hand, it doesn't
panic the kernel, as far as I know.

Convert prism2_usb firmware loading to load firmware in pre-compiled
binary 'ihex' format rather than ascii 'srec' format. This moves the
srec processing and sorting of records out of kernel space into a
pre-compiler. The driver now just works with the binary image, but
still does the 'pda plugging' of that image at runtime, as required
by the prism hardware.
Some Notes:
- The firmware is now expected to be in the same 'ihex' (.fw) format
used by other drivers.
- The now driver assumes the data records are already sorted into ascending
address order.
- Plug and crc records are still recognised by special address locations
as in original srec processing.
- The srec S7 start address record is assumed to have been converted
into a data record with another special address location (0xff400000),
with the original start address being stored as a 4 byte data word
(little endian).
