If anyone has any objections, please let me know. ------------------ From: Rafael J. Wysocki commit cdf65d73e001fde600b18d7e45afadf559425ce5 upstream. A subsequent change will need to pass a depth argument to acpi_execute_reg_methods(), so prepare that function for it. No intentional functional changes. Signed-off-by: Rafael J.
