From 02aa2a37636c8fa4fb9322d91be46ff8225b7de0 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 3 Jul 2013 15:04:56 -0700 Subject: drivers: avoid format string in dev_set_name Calling dev_set_name with a single paramter causes it to be handled as a format string. Many callers are passing potentially dynamic string content, so use "%s" in those cases to avoid any potential accidents, including wrappers like device_create*() and bdi_register().
