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 :). CJ

AFACIS: stmmac_config_{single,multi}_msi -> pci_alloc_irq_vectors -> pci_alloc_irq_vectors_affinity -> __pci_enable_msix_range -> pcim_setup_msi_release So LGTM, thanks! Paolo

When the managed API is used, there is no need to explicitly call pci_free_irq_vectors(). This looks to be a left-over from the commit in the Fixes tag. Only the .remove() function had been updated. So remove this unused function call and update goto label accordingly.
