ide: Fix irq flags madness
commit ec1a123 (IDE: pass IRQ flags to the IDE core) introduced the bogosity of passing unfiltered resource->flags to the irq_flags which are used for request_irq. It results in random bits set (especially IORESOURCE_IRQ which maps to IRQF_PER_CPU). Filter the bits proper. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: David S. Miller <davem@davemloft.net>
