Subject: [PATCH v2] checkpatch: don't complain on _Generic() use
Date:   Tue,  5 Dec 2023 12:05:24 +0100
Message-Id: <20231205110524.16561-1-przemyslaw.kitszel@intel.com>
MIME-Version: 1.0

Precedence: bulk

Improve CamelCase recognition logic to avoid reporting on _Generic() use.

Other C keywords, such as _Bool, are intentionally omitted, as those
should be rather avoided in new source code.

v2: _Static_assert dropped from the scope;
    whole word match.
