Linus,

please pull the latest irq/urgent branch from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq-urgent-2023-02-19

up to: 2b129f0b24ab: PCI/MSI: Provide missing stubs for CONFIG_PCI_MSI=n


A single fix for the PCI/MSI infrastructure:

The addition of the new alloc/free interfaces in this cycle forgot to
add stub functions for pci_msix_alloc_irq_at() and pci_msix_free_irq()
for the CONFIG_PCI_MSI=n case


Thanks,

tglx
