Subject: [PATCH 3/11][TG3]: Clear GPIO mask before storing.
Date: Fri, 04 May 2007 17:52:38 -0700 [thread overview]
Message-ID: <1178326358.4859.19.camel@dell> (raw)
[TG3]: Clear GPIO mask before storing.
The GPIO settings may change during reset and so the stored values in
tp->grc_local_ctrl should be cleared first.
