From 4b59cc1fd6fd1dac1d4468b4f327ae9f59d1c0aa Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sun, 3 Mar 2013 23:06:21 +0100 Subject: [PATCH] ACPI / scan: Introduce acpi_scan_handler_matching() Introduce new helper routine acpi_scan_handler_matching() for checking if the given ACPI scan handler matches a given device ID and rework acpi_scan_match_handler() to use the new routine (that routine will also be useful for other purposes in the future).
