From e44df9296a8ab9d9160e230d68a1b01015c94e93 Mon Sep 17 00:00:00 2001 From: Ivo van Doorn Date: Sun, 10 Feb 2008 22:50:04 +0100 Subject: rt2x00: Fix scheduling while atomic errors in usb drivers Call rt2x00_config_intf() outside of the spinlock context since the call will sleep for USB drivers. By using the ieee80211_if_conf values as arguments we make keep access tp rt2x00_intf thread safe even without the lock. Signed-off-by: Ivo van Doorn Signed-off-by: John W.
