Philipp Stanner Oct. 15, 2024, 6:51 p.m. UTC 
pci_intx() and its managed counterpart pcim_intx() only exist for older
drivers which have not been ported yet for various reasons. Future
drivers should preferably use pci_alloc_irq_vectors().

Mark pci_intx() and pcim_intx() as deprecated and encourage usage of
pci_alloc_irq_vectors() in its place.
