iwlwifi: fix oops in iwl3945_led_brightness_set
fix race between: ieee80211_open->ieee80211_led_radio->led_trigger_event->led_set_brightness->iwl3945_led_brightness_set (which assumes that "led->priv" is not NULL) and iwl3945_pci_probe->iwl3945_setup_deferred_work->(...)->iwl3945_bg_alive_start->iwl3945_alive_start->iwl3945_led_register->iwl3945_led_register_led which sets priv field in struct iwl3945_led after led->led_dev.brightness_set = iwl3945_led_brightness_set; (...) led_classdev_register(device, &led->led_dev); http://kerneloops.org/guilty.php?guilty=iwl3945_led_brightness_set&version=2.6.25-release&start=1671168&end=1703935&class=oops Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Cc: Zhu Yi <yi.zhu@intel.com> Cc: Reinette Chatre <reinette.chatre@intel.com> Cc: Tomas Winkler <tomas.winkler@intel.com> Cc: linux-wireless@vger.kernel.org Cc: ipw3945-devel@lists.sourceforge.net Signed-off-by: John W.
