Subject: [PATCH 5.15 2/3] can: m_can: make custom bittiming fields const
Date: Mon, 20 Dec 2021 10:22:16 +0100 [thread overview]
Message-ID: <a5f7f14b1122056399484f2a8e16bd4d7de6e15e.1639990483.git.matthias.schiffer@ew.tq-group.com> (raw)
In-Reply-To: <cover.1639990483.git.matthias.schiffer@ew.tq-group.com>
commit ea22ba40debee29ee7257c42002409899e9311c1 upstream.
The assigned timing structs will be defined a const anyway, so we can
avoid a few casts by declaring the struct fields as const as well.
