[PATCH] ymfpci.c MODULE_DEVICE_TABLE

From: Peter Samuelson (peter@cadcamlab.org)
Date: Tue Dec 05 2000 - 02:13:52 EST


Adam, could you check my work here? I haven't done this before.... It
compiles, but I don't have the hardware to verify anything. And, being
a lousy kernel hacker, I've probably introduced at least one bug.

Peter
