From 6cda08a20dbde45b021091230c8a359fa08c5103 Mon Sep 17 00:00:00 2001 From: Suzuki K Poulose Date: Tue, 23 Jul 2019 23:18:32 +0100 Subject: drivers: Introduce device lookup variants by name Add a helper to match the device name for device lookup. Also reuse this generic exported helper for the existing bus_find_device_by_name(). and add similar variants for driver/class.
