3.16.84-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Chuhong Yuan <[email protected]> commit 7f8c36fe9be46862c4f3c5302f769378028a34fa upstream. Since tasklet is needed to be initialized before registering IRQ handler, adjust the position of tasklet_init to fix the wrong order. Besides, to fix the missed tasklet_kill, this patch adds a helper function and uses devm_add_action to kill the tasklet automatically.
