Subject: [RFC PATCH 2/7] i2c: use DEFINE for the dummy driver name
Date: Thu, 20 Feb 2020 18:23:58 +0100 [thread overview]
Message-ID: <20200220172403.26062-3-wsa+renesas@sang-engineering.com> (raw)
In-Reply-To: <20200220172403.26062-1-wsa+renesas@sang-engineering.com>
We use it in multiple places, so make sure it is consistent whenever we
need to change it.
