Hi,

I've looked at it again.

I still think that the patch is good, but pcim_release() has changed in 
5.18 since commit 3f35d2cf9fbc ("PCI/MSI: Decouple MSI[-X] disable from 
pcim_release()")

I guess that all the mechanic is in place so that everything is 
registered when needed, but I've not been able to figure it out in the 
case of dwmac-intel.c.

So, double check :).
