From 8cec0e7b4c7c0b76f2b5285f250211ad81c3eafd Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Tue, 8 Jun 2010 07:48:17 -0600 Subject: of/device: Add OF style matching helper function Add of_driver_match_device() helper function. This function can be used by bus types to determine if a driver works with a device when using OF style matching. If CONFIG_OF is unselected, then it is a nop.
