I've been trying to make the parport_cs kernel module work with the 2.4
series kernel and came across a problem in the parport_pc.c file.
In the 2.2 kernel series check_region, request_region and other
functions like it are declared as functions returning void.
In the 2.4 kernel series these functions return a pointer value so that
an error can be signaled, if a NULL pointer is returned the check or
In the parport_pc.c file the parport_pc_probe_port function does a "if (
check_region(base,3) ) return NULL;" which I think should be "if (
!check_region(base,3) ) return NULL;"
If I apply this crude hack to parport_pc.c and modify parport_cs.c so it
known there are only 3 parport modes (compared to 5 in the 2.2 kernel
series) the pcmcia parport module works just fine
The way I have to implement this patch is so ugly that I thing this
problem might affect other parport function.
any comments are welcome,
