From b9d41052794385f9d47ebb7acf4a772f3ad02398 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Mon, 13 Dec 2010 13:42:24 -0600 Subject: dlm: sanitize work_start() in lowcomms.c The create_workqueue() returns NULL if failed rather than ERR_PTR(). Fix error checking and remove unnecessary variable 'error'.
