  It is not used outside of its compilation unit, so there's no need to
export this variable.

Yeah, I added the EXPORT for the regulator code to use it in
dca0b44957e5 but that got backed out when setting
driver_deferred_probe_timeout to 30s was reverted, and this bit was
forgotten.

Thanks for catching this!

Could you please pick this patch? Is a fix independent of the other
patches in the series and it has already been acked by John.

It is the middle of the merge window and I can't take anything now until
after 6.2-rc1 is out.  I also really can't take individual patches out
of a patch series easily, so please just resend it as a single patch
when 6.2-rc1 is out.

thanks,

greg k-h
