[PATCH AUTOSEL 6.12 16/20] ACPI: resource: acpi_dev_irq_override(): Check DMI match last

[Sasha Levin <sashal@kernel.org>]

From: Hans de Goede <hdegoede@redhat.com>

[ 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.
