update checkpatch to version 0.26

This update brings a couple of new checks, and a number of fixes.  Of note:

 - allows parentheses on return of comparisons
 - tracks #ifdef sections better
 - fixes miss reports of variables containing static

It also updates the maintainers entry to track my new email address and
to drop inactive maintainers.

Complete changelog below.
