[PATCH] create_workqueue_thread() signedness fix
With "-W -Wno-unused -Wno-sign-compare" I get the following compile warning:
CC kernel/workqueue.o
kernel/workqueue.c: In function `workqueue_cpu_callback':
kernel/workqueue.c:504: warning: ordered comparison of pointer with integer zero
On error create_workqueue_thread() returns NULL, not negative pointer, so
following trivial patch suggests itself.
