From 7236214c88454d96de7633e07a8314644d529f26 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Wed, 9 Sep 2015 23:42:06 +0200 Subject: [PATCH] PM / wakeup: wakeup_source_create: use kstrdup_const Using kstrdup_const allows us to save a little runtime memory (and a string copy) in the common case where name is a string literal.
