Subject: [PATCH 4/5] i2c: mv64xxx: directly call send_start when initializing transfer
Date: Thu, 13 Feb 2014 21:36:32 +0100 [thread overview]
Message-ID: <1392323793-4125-5-git-send-email-wsa@the-dreams.de> (raw)
In-Reply-To: <1392323793-4125-1-git-send-email-wsa@the-dreams.de>
Calling the state machine with a definite state which is only used in
this context is superfluous. Do it directly.
