[Tarantool-patches] [PATCH 2/2] ci: enable checkpatch

[Sergey Bronnikov]

From: Sergey Bronnikov <sergeyb at tarantool.org>

Patch enables checkpatch [1] for checking patch on a pre-commit stage.
In Tarantool we use our own fork of checkpatch [2] with additional check
types. It's logical to use it in a LuaJIT development. We don't need
check tags in commit messages like NO_DOC, NO_CHANGELOG, NO_TEST and
others, so to be able to customize command-line options Github Action, provided
by checkpatch repository [3], was added to the repository.

See documentation for used checkpatch in [4].
