[PATCH] gamecon.c change for SNES controller

[PATCH] gamecon.c change for SNES controller

[Eduardo]

Pavlik -

I've had to applie the following change to make the SNES controller work 
at the parallel port. It have been applied to two computers. The old 
code was giving the same values when you pressed right or left or when 
you pressed up or down. The new code have been done to not use expensive 
codification (i.e. multiplication).

It have been applied to kernel 2.4.6, and compiled with gcc 3.0.

See ya,
