Fix some coding style issues reported by checkpatch.pl

following types:
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: Missing a blank line after declarations
First of all, two changes ==> two patches.
I thought it would be better to include more simple cleanup in one patch.

How did you test this? Is there any guarantee that input is
null-terminated number?
Where is the check of returned value from `kstrtol()`?
Yes, you haven’t tested that at all. Don’t submit patches you are not
able to test and haven’t tested.
It's my fault. Sorry for that, i will fix it.
NAK.
