Subject: update checkpatch.pl to version 0.18
From: Andy Whitcroft <apw@xxxxxxxxxxxx>
This version brings a few fixes for the extern checks, and a couple of
new checks.
Of note:
- false is now recognised as a 0 assignment in static/external
assignments,
- printf format strings including %L are reported,
- a number of fixes for the extern in .c file detector which had
temporarily lost its ability to detect variables; undetected due to
the loss of its test.
Andy Whitcroft (8):
Version: 0.18
false should trip 0 assignment checks
tests: reinstate missing tests
tests: allow specification of the file extension for a test
fix extern checks for variables
check for and report %Lu, %Ld, and %Li
ensure we only start a statement on lines with some content
extern spacing
