checkpatch.pl still reports the below in_atomic warning:
WARNING: use of in_atomic() is incorrect outside core kernel code
+ if (in_atomic())
But, in_atomic() has been used outside kernel dir for a long time, and
even drivers. So, remove the obsolete rule even though they can be
ignored.

Not sure if removing the obsolete rule is preferred by checkpatch.pl, anyway
it sounds not make sense to keep invalid rule.
