#4 Make ftdi_sio-1.3.4 work on 2.4.19 kernel

[Ian Abbott]

This patch to the ftdi_sio-1.3.4 sources allows them to be used with
a 2.4.19 kernel.

To use:

1. Grab the ftdi_sio-1.3.4 sources from patch item 824033 (or by
copying ftdi_sio.c and ftdi_sio.h from a 2.4.22 kernel).

2. Apply the patch ftdi_sio-1.3.4-2.4.19.patch to the ftdi_sio-1.3.4
sources.

3. Assuming you have a 2.4.19 kernel source directory configured
to match the kernel you want to use, copy the patched ftdi_sio.c
and ftdi_sio.h files into this kernel source tree (in directory
drivers/usb/serial). You may wish to back up the old versions first.

4. Go to the root of the kernel source tree, rebuild the modules
('make modules') and install them ('make modules_install').

5. Run 'depmod -a' and 'rmmod ftdi_sio' for good luck, and plug in
your USB serial device. If the USB hotplug mechanism doesn't load
the module, run 'modprobe ftdi_sio'.

6. Run 'dmesg' to check that the FTDI driver reports itself as
version 1.3.4.
