[libcamera-devel] [PATCH v3 6/6] checkstyle: Add a pre-commit hook script

[Nicolas Dufresne]

From: Nicolas Dufresne <nicolas.dufresne at collabora.com>

This adds support for pre-commit hook workflow. In pre-commit hook we
check the style on the changes currently staged or the combination
of the index and the last commit if "git commit --amend" is being used.
