Subject: [PATCH 3.14 160/228] ARM: mvebu: mvebu-soc-id: add missing clk_put() call
3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Petazzoni <thomas.petazzoni@...e-electrons.com>
commit 42a18d1cf484d02e23afadfa5dc09356e6bef9fa upstream.
The mvebu-soc-id code in mach-mvebu/ needs to enable a clock to read
the SoC device ID and revision number. To do so, it does a clk_get(),
then a clk_prepare_enable(), reads the value, and disables the clock
with clk_disable_unprepare(). However, it forgets to clk_put() the
clock. This commit fixes this issue.
