Subject: [RFC PATCH 4/7] i2c: of: remove superfluous parameter from exported function
Date:   Thu, 20 Feb 2020 18:24:00 +0100
Message-Id: <20200220172403.26062-5-wsa+renesas@sang-engineering.com>
In-Reply-To: <20200220172403.26062-1-wsa+renesas@sang-engineering.com>

Precedence: bulk

'dev' is only used for printing an error message. However, that
information is not needed because '%pOF' fully describes the location of
the error. Drop the 'dev' and remove the superfluous parameter.
