From 20991cdb26ffc51030223320a6dd266f4fc28fbd Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Wed, 30 Sep 2015 20:30:26 +0200 Subject: [PATCH] regmap: debugfs: use memcpy instead of snprintf Since we know the length of entry and that there's room enough in the output buffer, using memcpy instead of snprintf is simpler and cheaper.
