From 35f045f9783d22a94de7a8ac173db67e41cfd258 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Sat, 10 Aug 2024 02:43:59 +0300 Subject: utils: checkstyle.py: Skip title and trailers checkers for pre-commit When running checkstyle.py in a pre-commit hook, there is either no commit message at all (when committing staged changes as a new commit), or the commit message comes from a previous commit being amended. In either case, there's no new commit message yet, and thus nothing to validate for the title and trailers checkers. The trailers checker, in particular, will always flag an error, making all commits fail. To fix that, just skip the two checkers during pre-commit.
