From f256280006afbf51ddf267c69ca4f5b229696c7c Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Thu, 10 Dec 2015 09:22:49 +0100 Subject: [PATCH] linux/barebox-wrapper: Silence gcc5 warning gcc5 warns about using flags uninitialized in spin_lock_irqsave, although it could look into the static inline spin_lock_irqsave implementation and see it's not used at all. An empty define instead of the static inline wrapper would lead to a "unused variable" warning. Let's create a macro and fake some usage of the flags variable. This probably helps until gcc6 is out.
