Subject: [PATCH] sky2: Make hw->ports the number of ports allocated
Date: Sat, 12 Sep 2009 12:19:23 +0900 [thread overview]
Message-ID: <4AAB133B.8070900@ring3k.org> (raw)
If allocation of the second ports fails, make sure that hw->ports
is not 2 otherwise we'll crash trying to access the second port.
