From 4d66edc8b6c0622ed6df74709de65f70d1ca222f Mon Sep 17 00:00:00 2001 From: Gertjan van Wingerde Date: Tue, 30 Mar 2010 23:50:26 +0200 Subject: [PATCH] rt2x00: Add wakeup interrupt handler to rt2800pci. This is needed to wake up the device automatically for receiving beacons, and is required for proper powersave handling. Signed-off-by: Gertjan van Wingerde Signed-off-by: John W.
