Subject[PATCH 4.4 73/78] thermal: hisilicon: Handle return value of clk_prepare_enable
Date
4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arvind Yadav <arvind.yadav.cs@gmail.com>

commit 919054fdfc8adf58c5512fe9872eb53ea0f5525d upstream.

clk_prepare_enable() can fail here and we must check its return value.
