I think it's better to use as labels what will be done in the error path
rather than what failed. IOW, "disable_axius_clk" or "disable_clks" are
more clear than vdd33_err for me, since can give you an idea of what will
happen in the error path.

But I don't have a strong opinion and your naming is an improvement over
the current one, so:

doesn't apply to testing/next, please rebase.

Hi Felipe,

This patch is dependent on the

usb: dwc3: exynos fix axius clock error path to do cleanup
https://lkml.org/lkml/2017/1/10/1081

The above made it into usb-linus. It will apply to usb-next
or usb-testing after it gets merged. I can resend it after
the dependent patch makes it into the next rc release.

thanks,
