Message-Id: <1398114703-32410-3-git-send-email-elder@linaro.org>
Date: Mon, 21 Apr 2014 16:11:38 -0500
From: Alex Elder <elder@...aro.org>
To: mturquette@...aro.org, mporter@...aro.org, bcm@...thebug.org
Cc: linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org
Subject: [PATCH v4 RESEND 2/7] clk: bcm281xx: use init_data.name for clock name
Use the init_data.name field to hold the name of a Kona clock rather
than duplicating it.
Signed-off-by: Alex Elder <elder@...aro.org>
