Subject: [PATCH] au1000_eth: fix invalid address accessing the MAC enable register
Date: Tue, 23 Nov 2010 17:40:25 +0100 [thread overview]
Message-ID: <4CEBEE79.8040507@grandegger.com> (raw)
"aup->enable" holds already the address pointing to the MAC enable
register. The bug was introduced by commit d0e7cb:
"au1000-eth: remove volatiles, switch to I/O accessors".
