So many of the architecutres where it is defined do not use it. This also means we can remove asm-generic/pci.h as all it provides is a definition of pci_get_legacy_ide_irq. Where referenced, replace the usage of pci_get_legacy_ide_irq with the libata.h macros ATA_PRIMARY_IRQ and ATA_SECONDARY_IRQ which provide the same functionality. This allows removing pci_get_legacy_ide_irq from headers where it is no longer used. Acked-by: Geert Uytterhoeven Acked-by: Pierre Morel Acked-by: Rafael J.
