Subject: [PATCH V9 RESEND 10/14] thermal: tegra: handle clocks in one function
Date: Tue, 29 Mar 2016 18:29:20 +0800	[thread overview]
Message-ID: <1459247364-1139-11-git-send-email-wni@nvidia.com> (raw)
In-Reply-To: <1459247364-1139-1-git-send-email-wni@nvidia.com>

Handle clock enable/disable codes in one function
soctherm_clk_enable(), so that the codes are more clear.
