Subject: ACPI: enumerate namespace before adding functional fixed hardware devices
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=adc08e2035f1859d4b129f42b2c2305ef090d226;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ACPI: enumerate namespace before adding functional fixed hardware devices

This patch changes the order so we enumerate in the "root, namespace,
functional fixed" order instead of the "root, functional fixed, namespace"
order.  When I change acpi_bus_scan() to use acpi_walk_namespace(), it
will use the former order, so this patch isolates the order change for
bisectability.
