From d8537548c924db3c44afde7646b6e220c7beb79d Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 3 Jul 2013 15:04:57 -0700 Subject: drivers: avoid format strings in names passed to alloc_workqueue() For the workqueue creation interfaces that do not expect format strings, make sure they cannot accidently be parsed that way. Additionally, clean up calls made with a single parameter that would 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.
