From a65ecc4070c75ed53553def79e5da862b47daf1f Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 25 Feb 2016 10:47:10 +0300 Subject: [PATCH] drm/amd: cleanup get_mfd_cell_dev() It's simpler to just use snprintf() to print this to one buffer instead of using strcpy() and strcat(). Also using snprintf() is slightly safer than using sprintf().
