Since commit 7ef9651e9792 ("clk: Provide new devm_clk helpers for
prepared and enabled clocks"), devm_clk_get() and clk_prepare() can now be
replaced by devm_clk_get_prepared() when the driver enables (and possibly
prepares) the clocks for the whole lifetime of the device. Moreover, it is
no longer necessary to unprepare and disable the clocks explicitly.

The commit message isn't correct. Seems you copied'n'pasted from other cases.

Please, revisit.

Code wise looks legit to me.
