checkpatch errors regarding the existing code base are not relevant as a rule.

Now, this patch removes unnecessary empty lines, so it is not
meritless, but it should go under a different subject and with a
changelog describing what's going on.

Something like

Subject: [PATCH] cpuidle: Remove unnecessary empty lines preceding
EXPORT_SYMBOL_GPL()

In several places in cpuidle.c there are empty lines between the
definition of a function and the following EXPORT_SYMBOL_GPL() which
are not necessary, so remove them.
