Subject: [PATCH v3 02/14] lib/vsprintf.c: move string() below widen_string()
Date: Thu,  3 Dec 2015 21:51:01 +0100	[thread overview]
Message-ID: <1449175873-1780-3-git-send-email-linux@rasmusvillemoes.dk> (raw)
In-Reply-To: <1449175873-1780-1-git-send-email-linux@rasmusvillemoes.dk>

This is pure code movement, making sure the widen_string() helper is
defined before the string() function.
