[PATCH 4/4] ACPI, PCI, IRQ: add PCI_USING for ISA interrupts too

From: Sinan Kaya
Date: Wed Sep 28 2016 - 19:27:41 EST

The change introduced in commit 103544d86976 ("ACPI,PCI,IRQ: reduce
resource requirements") removed PCI_USING penalty from
acpi_pci_link_allocate function as there is no longer a fixed size penalty
array for both PCI and IRQ interrupts.

We need to add the PCI_USING penalty for ISA interrupts too if the link is
in use and matches our ISA IRQ number.
