From be25d875b924cbd50d49fd9f343e70d86b7ad7e0 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 12 Nov 2014 18:26:50 -0700 Subject: [PATCH] Add pr_fmt() macro This macro can be overridden in source files (before including common.h) and can be used to specify a prefix for debug and error messages. An example of how to use this is shown below: #define pr_fmt(fmt) "foo: " fmt #include ... debug("bar"); The resulting message will read: foo: bar Acked-by: Simon Glass Signed-off-by: Thierry Reding Signed-off-by: Simon Glass --- include/common.h | 14 +++++++++----- 1 file changed, 9 insertions(+), 5 deletions(-) diff --git a/include/common.h b/include/common.h index ce0a734..f1ab2cf 100644 --- a/include/common.h +++ b/include/common.h @@ -97,15 +97,19 @@ typedef volatile unsigned char vu_char; #define _DEBUG 0 #endif +#ifndef pr_fmt +#define pr_fmt(fmt) fmt +#endif + /* * Output a debug text when condition "cond" is met.
