Subject: [PATCH] ubifs: Initialize fstr_real_len
Date: Wed, 14 Dec 2016 11:09:25 +0100	[thread overview]
Message-ID: <20161214100925.10797-1-richard@nod.at> (raw)

While fstr_real_len is only being used under if (encrypted),
gcc-6 still warns.

Fixes this false positive:
fs/ubifs/dir.c: In function 'ubifs_readdir':
fs/ubifs/dir.c:629:13: warning: 'fstr_real_len' may be used
uninitialized in this function [-Wmaybe-uninitialized]
    fstr.len = fstr_real_len

Initialize fstr_real_len to make gcc happy.
