sched.h changes in 2.4.19rc5aa1 / Digi's cpci driver doesn't compile

[Pasi Kärkkäinen]

Hello!

I'm using Linux 2.4.19rc5aa1 and having problems to compile Digi's cpci
driver for multiport serialboard. This driver is not part of the kernel,
but available from Digi's website.

The problem seems to be related to changes in include/linux/sched.h.
Digi's driver wants to use member called "counter" which doesn't exist
anymore in the -aa kernel.

The code goes like this (cpci.c line 3847):

	current->state = TASK_INTERRUPTIBLE;
	current->counter = 0;   /* make us low-priority */

current is task_struct.

Sources available from http://nrg.joroinen.fi/digi/

Any ideas how to fix this? I'm not familiar with kernel driver
development..

Its assuming old old scheduler bits. I suspect just removing the
current->counter junk will make it happy

I removed that line, and then it compiled OK and it seems to work too.

Thank you!

ps. If somebody from Digi is reading this, why don't you send these
drivers for inclusion to the kernel?
