[ Upstream commit cd4a7b2e6a2437a5502910c08128ea3bad55a80b ]
acpi_dev_irq_override() gets called approx. 30 times during boot (15 legacy IRQs * 2 override_table entries). Of these 30 calls at max 1 will match the non DMI checks done by acpi_dev_irq_override(). The dmi_check_system() check is by far the most expensive check done by acpi_dev_irq_override(), make this call the last check done by acpi_dev_irq_override() so that it will be called at max 1 time instead of 30 times.
