Subject: [PATCH 01/11] i2c: rcar: not everything needs to be a function
Date: Wed, 28 May 2014 09:44:36 +0200 [thread overview]
Message-ID: <1401263086-13720-2-git-send-email-wsa@the-dreams.de> (raw)
In-Reply-To: <1401263086-13720-1-git-send-email-wsa@the-dreams.de>
From: Wolfram Sang <wsa+renesas@sang-engineering.com>
Very basic operations, just called once, can also go to the caller.
