Subject: [RFC PATCH v2 1/6] i2c: use DEFINE for the dummy driver name
Date: Wed, 18 Mar 2020 16:00:54 +0100	[thread overview]
Message-ID: <20200318150059.21714-2-wsa+renesas@sang-engineering.com> (raw)
In-Reply-To: <20200318150059.21714-1-wsa+renesas@sang-engineering.com>

We use it in multiple places, so make sure it is consistent whenever we
need to change it.
