[patch 050/176] iwlagn: Re-enable RF_KILL interrupt when down

[Greg KH]

2.6.36-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Don Fry <donald.h.fry@xxxxxxxxx>

commit 3dd823e6b86407aed1a025041d8f1df77e43a9c8 upstream.

With commit 554d1d027b19265c4aa3f718b3126d2b86e09a08 only one RF_KILL
interrupt will be seen by the driver when the interface is down.

Re-enable the interrupt when it occurs to see all transitions.
