Change stm32-usbphyc driver to defer its probe when the expected reset
control has its probe operation deferred.

I'm sorry for the mess, I sent a v2 for the patch 1/2: 
https://lore.kernel.org/patchwork/patch/1336206/
Indeed, I forgot the "return" before dev_err_probe.

Do you want me to send a fix?

Regards,
Amelie

No worries, I have dropped this and picked v2.
Do check if the patches are fine.

Thanks for letting me know
