ACPI / bind: Redefine acpi_preset_companion()
Modify acpi_preset_companion() to take a struct acpi_device pointer instead of an ACPI handle as its second argument and redefine it as a static inline wrapper around ACPI_COMPANION_SET() passing the return value of acpi_find_child_device() directly as the second argument to it. Update its users to pass struct acpi_device pointers instead of ACPI handles to it. This allows some unnecessary acpi_bus_get_device() calls to be avoided. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Reviewed-by: Aaron Lu <aaron.lu@intel.com> Tested-by: Aaron Lu <aaron.lu@intel.com> # for ATA binding
