Subject: [PATCH v1 1/4] can: ctucanfd: remove PCI module debug parameters and core debug statements
Date:   Sun, 24 Apr 2022 18:28:08 +0200
Message-Id: <1fd684bcf5ddb0346aad234072f54e976a5210fb.1650816929.git.pisa@cmp.felk.cvut.cz>

Content-Transfer-Encoding: 8bit
Precedence: bulk

This and remove of inline keyword from the local static functions
should make happy all checks in actual versions of the both checkpatch.pl
and patchwork tools.
