From d8ed9e87e6016433b8d178728a5391ea68101bca Mon Sep 17 00:00:00 2001 From: LABBE Corentin Date: Tue, 16 Aug 2016 11:27:18 +0200 Subject: fbdev: ssd1307fb: 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.
