From 9aed5080834a4e848a88b972738f28dce466b420 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 27 Sep 2012 17:08:15 +0200 Subject: COMMON: Add __stringify() function Copied from Linux kernel: commit 8f7c2c37319a81ef4c2bfdec67b1ccd5744d97e4 Date: Wed Apr 8 16:58:57 2009 +0800 Pull in the __stringify() macro from Linux kernel. This macro is usually used to convert numbers to strings at preprocessor level, yet it is not limited only to that. This is useful as it allows higher usage of puts() in favour of printf().
