Subject[PATCH v2] clk: mvebu: armada-37xx-tbg: Switch to clk_get and balance it in probe
Date
The parent clock is get only to have its name, and then the clock is no
more used, so we can safely free it using clk_put. Furthermore as between
the successful devm_clk_get() and the devm_clk_put() call we don't exit
the probe function in error so I can use non managed version of clk_get()
and clk_put().

Signed-off-by: Gregory CLEMENT <gregory.clement@bootlin.com>

Changelog:
v1 -> v2

- Use the non managed version of clk_get() and clk_put() (suggested
by Stephen Boyd)
- Modify the title and the commit log to reflect this change
