[PATCH v3 3/7] acpi: add acpi_of_match_device_ids

[Markus Probst via B4 Relay]

From: Markus Probst <markus.probst@xxxxxxxxx>

Add a function to match acpi devices against of_device_ids. This will be
used in the following commit ("mfd: match acpi devices against PRP0001")
to match mfd sub-devices against a of compatible string.
