From 2f6fe93fede802acfe010752db461ccd34745745 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Mon, 13 Jun 2022 20:10:03 +0200 Subject: ACPI: glue: Introduce acpi_find_child_by_adr() Rearrange the ACPI device lookup code used internally by acpi_find_child_device() so it can avoid extra checks after finding one object with a matching _ADR and use it for defining acpi_find_child_by_adr() that will allow the callers to find a given ACPI device's child matching a given bus address without doing any other checks in check_one_child().
