[PATCH] libata: set IRQF_SHARED for legacy PCI IDE IRQs
There are machines out there which share legacy PCI IDE IRQs w/ other devices. libata SFF interrupt/HSM code is ready for shared IRQ and has been setting IRQF_SHARED for devices in native PCI mode. Device in legacy mode is still a PCI device and thus supposedly uses active-low level triggered IRQ. Machines with such setup should be quite rare and w/o this flag libata is likely to fail loading and render the system unuseable. Also, IDE driver has been setting IRQF_SHARED for devices in legacy mode for a looooong time. Signed-off-by: Tejun Heo <htejun@gmail.com>
