The call to clk_disable_unprepare is incorrect in the current code. The
way you worded that, it sounds like it's no longer needed because of the
changes made in this patch. I would re-write that last sentence as:
Remove the call to clk_disable_unprepare(); this function does not
prepare or enable the clock, so the error path should not disable or
unprepare it.
