[PATCH] Change "return EBLAH" to "return -EBLAH in drivers/*

[Anthony J. Breeds-Taurima]

Hello All,
	This is a simple patch that changes several "return EBLAH"'s in drivers/*
for "return -EBLAH".  I have done my best to check the call stack to ensure
that the change in sign of the return values wont break anything.

The patch supplied is agaist linux-2.4.19-pre6

Yours Tony.
