From 9e18944601856c04c07dc569b87e9b98e8a9da5f Mon Sep 17 00:00:00 2001 From: Gertjan van Wingerde Date: Tue, 30 Mar 2010 23:50:25 +0200 Subject: [PATCH] rt2x00: Add wakeup interrupt handler to rt61pci. 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.
