Alignment doesn't look right. Could you please run checkpatch on all
the patches?

Is it required to have this commit first prior to architecture
functionality? I am wondering whether it is logically better to
implement the function first and then consume in next commit?

I think this can be fit in single like as we can have upto 100
characters.

Seems something is wrong with my vim configuration.
Will fix it in v2.

No dependency between this commit and the next commit.
Will change the order in v2.
