From d741900d404b3a34bf478673f76ee9f16dad3f90 Mon Sep 17 00:00:00 2001 From: Jussi Kivilinna Date: Mon, 31 Jan 2011 20:47:17 +0200 Subject: zd1211rw: cancel process_intr work on zd_chip_disable_int() OOPS if worker is running and disconnect() is called (triggered by unpluging device). Much harder to trigger at this stage but later when we have AP beacon work in process_intr it happens very easy. Signed-off-by: Jussi Kivilinna Signed-off-by: John W.
