In the Linux kernel, the following vulnerability has been resolved:

ASoC: da7219: Fix an error handling path in da7219_register_dai_clks()

If clk_hw_register() fails, the corresponding clk should not be
unregistered.

To handle errors from loops, clean up partial iterations before doing the
goto.  So add a clk_hw_unregister().
Then use a while (--i >= 0) loop in the unwind section.
