Subject: kthread_work: remove the unused wait_queue_head
X-Git-Tag: omap-for-v3.17/fixes-against-rc2~192^2

kthread_work: remove the unused wait_queue_head

The wait_queue_head_t kthread_work->done is unused since
flush_kthread_work() has been re-implemented.  Let's remove it
including the initialization code.  This makes
DEFINE_KTHREAD_WORK_ONSTACK() unnecessary, removed.

tj: Updated description.  Removed DEFINE_KTHREAD_WORK_ONSTACK().
