From
Subjectupdate checkpatch to version 0.20
Date
Following this email is the next batch of updates to checkpatch.
This marks a change in how I intend to send updates. The previous
"single delta" update caused us to lose a patch from Greg KH (which is
re-included in this update), bad. By sending the actual patches we avoid
regressing anything I have missed, it also has the advantage of maintaining
individual changes to carry signoff more accurately and generally being
more transparent.

This version brings a few new checks and the usual slew of fixes for
false positives mostly in type detection. Of note:

- allow printk text strings to bust the width restrictions for
grepability,
- major fixes for possible type/modifier handling,
- trailing statement checks for case and default,
- trailing statement checks for for and while,
- spacing checks for square brackets '[' ']',
- conditions/loops indent checks, and
- checks for new use of __initcall.

Complete changelog below.
