From d9fa482e5913213c2686404238f7f9cdb14b6c6c Mon Sep 17 00:00:00 2001 From: Corentin LABBE Date: Wed, 20 Sep 2017 20:47:26 +0200 Subject: crypto: bcm - use of_device_get_match_data The usage of of_device_get_match_data reduce the code size a bit. Furthermore, it prevents an improbable dereference when of_match_device() return NULL.
