[ Upstream commit 7f98960c046ee1136e7096aee168eda03aef8a5d ]
A successful 'clk_prepare()' call should be balanced by a corresponding 'clk_unprepare()' call in the error handling path of the probe, as already done in the remove function.
More specifically, 'clk_prepare_enable()' is used, but 'clk_disable()' is also already called. So just the unprepare step has still to be done.
Update the error handling path accordingly.
