From dfffa587a6bcd84f2087f88e11600b0e8b0aa1ee Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Fri, 15 Jan 2016 16:58:10 -0800 Subject: err.h: add (missing) unlikely() to IS_ERR_OR_NULL() IS_ERR_VALUE() already contains it and so we need to add this only to the !ptr check. That will allow users of IS_ERR_OR_NULL(), to not add this compiler flag.
