Hi Tomi,
This patch is similar to my last patch which you have already queued
for 3.20. if you can revert that then i can send you a single patch
with all these three changes together.

i have noticed that but thought that will be again a different type of change in a single patch.
but now it seems that this patch will introduce a new checkpatch warning, so i should have corrected that in it.
i will send a v2.

No need for that, two separate patches is fine. So queued for 3.20.
