Bjorn Helgaas fe2cf598e6 PNPACPI: ignore _PRS interrupt numbers larger than PNP_IRQ_NR ... ACPI Extended Interrupt Descriptors can encode 32-bit interrupt numbers, so an interrupt number may exceed the size of the bitmap we use to track possible IRQ settings. To avoid corrupting memory, complain and ignore too-large interrupt numbers. There's similar code in pnpacpi_parse_irq_option(), but I didn't change that because the small IRQ descriptor can only encode IRQs 0-15, which do not exceed bitmap size. In the future, we could handle IRQ numbers greater than PNP_IRQ_NR by replacing the bitmap with a table or list.
