Subject: [RFC PATCH 5/7] i2c: of: error message unification
Date: Thu, 20 Feb 2020 18:24:01 +0100	[thread overview]
Message-ID: <20200220172403.26062-6-wsa+renesas@sang-engineering.com> (raw)
In-Reply-To: <20200220172403.26062-1-wsa+renesas@sang-engineering.com>

- don't prefix the device if %pOF is provided. That information is
  enough.
- move the prefix to pr_fmt
- change prefix from "of_i2c" to "i2c_of" because the code was moved
  out of the of-domain long ago
