goto out_thread is called before we take the lock. It causes a gcc warning: "kernel/irq/manage.c:858: warning: ‘flags’ may be used uninitialized in this function" [ tglx: Moved unlock before free_cpumask_var() ] Signed-off-by: Dan Carpenter <error27@gmail.com> LKML-Reference: <20110317114307.GJ2008@bicker> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
