Subject: [PATCH v7 04/14] arm/tegra: don't export clk_measure_input_freq
Date: Wed, 14 Dec 2011 17:03:16 +0200	[thread overview]
Message-ID: <1323875032-18221-5-git-send-email-pdeschrijver@nvidia.com> (raw)
In-Reply-To: <1323875032-18221-1-git-send-email-pdeschrijver@nvidia.com>

don't export clk_measure_input_freq as its functionality is also available
using clk_get_rate().
