This patch series adds a simple macro pm_runtime_last_busy_and_autosuspend()
which invokes pm_runtime_mark_last_busy() and pm_runtime_put_autosuspend()
sequentially. Then we do a tree wide update of current patterns which are
present. As evident from log below this pattern is frequent in the
kernel.

This series can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/slave-dma.git
topic/pm_runtime_last_busy_and_autosuspend

Fengguang's kbuild has tested it so it shouldn't break things for anyone.
Barring one patch (explictyly mentioned in its changelog) rest are simple
replacements.

If all are okay, this should be merged thru PM tree as it depends on macro
addition.

OK, I guess this is as good as it gets.

What tree would you like it go through?
