Subject: [PATCH] Fix scanf() formatstring for modern C version
Date: Tue, 3 Nov 2015 14:50:02 +0100 [thread overview]
Message-ID: <20151103135002.GA21871@dw> (raw)
mkfs.jffs2 is using an old assignment-allocation
modifier for scanf(). Add a check so this modifier
does not get confused with a float formatstring
on newer C standard (C99 onwards).
