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.
