Subject: Re: [PATCH 1/2] pci: export pci_dev_unlock() and the respective unlock

Hello Luis, Hello Bjorn,

Interesting timing, I currently have a very similar patch lying around though
with also exporting pci_dev_lock(). I'm planning to use that for upcoming
support of automatic PCI devices recovery on s390x following the
Documentation/PCI/pci-error-recovery.rst recovery flow. There too exprting
these functions would make the code simpler to grok in my opinion. So if Bjorn
accepts this there could soon be another user, not sure if one would want to
then already export pci_dev_lock() too or wait until my patches so it's not
exported without users.

Best regards,
Niklas Schnelle
