From 7922118f8f3e76eb6534e9221a6c9f496c0ae699 Mon Sep 17 00:00:00 2001 From: LABBE Corentin Date: Tue, 16 Aug 2016 15:53:18 +0200 Subject: [PATCH] memory: atmel-sdramc: fix a possible NULL dereference of_match_device could return NULL, and so cause a NULL pointer dereference later. For fixing this problem, we use of_device_get_match_data(), this will simplify the code a little by using a standard function for getting the match data.
