[PATCH v1] ACPI: scan: Use resource_type() for resource type checking

From: Rafael J. Wysocki

Date: Tue Dec 30 2025 - 04:57:38 EST


From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

To follow a well-established existing pattern, use resource_type() for
resource type checking in acpi_scan_claim_resources().

No intentional functional impact.
