Since commit 7ef9651e9792 ("clk: Provide new devm_clk helpers for prepared
and enabled clocks"), devm_clk_get() and clk_prepare_enable() can now be
replaced by devm_clk_get_enabled() when driver enable (and possibly
prepare) the clocks for the whole lifetime of the device. Moreover, it is
no longer necessary to unprepare and disable the clock explicitly, so drop
the label "err_irq".
