I looked quickly through the thread and I am not sure what is exactly
your problem. I understood that the Exynos dwc3 driver is leaking the
PHY. That is a good catch but your patch is not sufficient. You should
clean up starting from devm_clk_get() error. Unless you are fixing
this for different kernel version.

Please send an appropriate separate patch for fixing this. Your email
did not reach people, I think. Just make a patch, test it,
scripts/checkpatch and scripts/get_maintainers. It is a fix so also a
candidate for this release cycle. if you do not plan to send a patch,
I can prepare on my own with your "Reported-by" tag but actually this
is your finding so credits (and effort) should go to you. :)

What other problems exactly do you have? Late binding of S2MPS11
regulator driver? That does not look like a problem. If it is built as
a module then it should be loaded, probably from initramfs because
these are regulators.

Best regards,
Krzysztof
