2021-06-07ACPI: scan: Extend acpi_walk_dep_device_list()Daniel Scally1-11/+11
The acpi_walk_dep_device_list() function is not as generic as its name implies, serving only to decrement the dependency count for each dependent device of the input. Extend it to accept a callback which can be applied to all the dependencies in acpi_dep_list. Replace all existing calls to the function with calls to a wrapper, passing a callback that applies the same dependency reduction.
