From e578e9a1cc8a5983d87126d5877e305d3189f1b9 Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Wed, 23 May 2007 13:58:05 -0700 Subject: [PATCH] i2o: destroy event queue only when drv->event is set i2o_driver_register() initalizes event queue for driver only when drv->event is set. So similarly the event queue should be destroyed only when drv->event is set in the error path. Otherwise destroy_workqueue() will called with NULL.
