[PATCH] platform: x86: Replace acpi_bus_get_device()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

Replace acpi_bus_get_device() that is going to be dropped with
acpi_fetch_acpi_dev().

No intentional functional impact.
