#2 Unofficial combined patches from 1.3.3 (1.3.4-pre-ia2)

[Ian Abbott]

Since the last version of my combined patch against v1.3.3 on
2003-06-13 (ftdi_sio-1.3.4-pre-ia1), the following changes have
been made:

- copied "USB relais" PID over from the version of ftdi_sio in the
2.5.x kernel;
- moved the bulk read transfer buffer reallocation out of the open
function and into the startup function;
- freed the old write urb and bulk write transfer buffer in the startup
function;
- halted write urb pool allocation as soon as soon as one urb
allocation fails, and modified loops that search the write urb pool to
take account of this;
- moved PKTSZ and BUFSZ macros;
- one or two minor whitespace and comment fixes;
- added Erik Nygren's fixed baud rate changes for USB-UIRT and
Tira-1.

These combined patches are slightly out-of-date now. The version of the
driver in kernel 2.4.22-pre3 and later is better.
