Subject: [PATCH V9 10/14] thermal: tegra: handle clocks in one function
Date: Tue, 29 Mar 2016 17:18:13 +0800 [thread overview]
Message-ID: <1459243093-25554-1-git-send-email-wni@nvidia.com> (raw)
Handle clock enable/disable codes in one function
soctherm_clk_enable(), so that the codes are more clear.
