Subject: gianfar: do not advertise any alarm capability.
From: Richard Cochran <richardcochran@xxxxxxxxx>
commit cd4baaaa04b4aaa3b0ec4d13a6f3d203b92eadbd upstream.
An early draft of the PHC patch series included an alarm in the
gianfar driver. During the review process, the alarm code was dropped,
but the capability removal was overlooked. This patch fixes the issue
by advertising zero alarms.
This patch should be applied to every 3.x stable kernel.
