[RESEND][PATCH v2 27/36] drivers: Add a generic helper to match device by fwnode handle

From: Suzuki K Poulose
Date: Tue Apr 16 2019 - 06:40:01 EST


Make the device_fwnode_match() a generic helper to match device
by fwnode handle for use with bus_find_device(). This will be
also used by coresight.
