Subject: [PATCH] 82596: free nonexistent resource fix

During booting of last vanilla kernel I got:
Trying to free nonexistent resource...

This because of if "ENABLE_APRICOT" is on we do:
request_region(ioaddr,...)
if (checksum test failed)
  goto out1;
dev->base_addr = ioaddr;//<-here mistake

out1:
release_region(dev->base_addr,...)

Here patch which fixes this bug for me.
