[ 01/56] UBIFS: fix compilation warning

From: Greg Kroah-Hartman
Date: Fri Nov 30 2012 - 14:29:13 EST


3.4-stable review patch. If anyone has any objections, please let me know.

------------------

From: Alexandre Pereira da Silva <aletes.xgr@xxxxxxxxx>

commit 782759b9f5f5223e0962af60c3457c912fab755f upstream.

Fix the following compilation warning:

fs/ubifs/dir.c: In function 'ubifs_rename':
fs/ubifs/dir.c:972:15: warning: 'saved_nlink' may be used uninitialized
in this function

Use the 'uninitialized_var()' macro to get rid of this false-positive.

Artem: massaged the patch a bit.
