Subject: [PATCH] ncpfs: fix wrong check in __ncp_ioctl()
Date: Tue, 28 Jul 2009 17:05:34 +0200	[thread overview]

From: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
Subject: [PATCH] ncpfs: fix wrong check in __ncp_ioctl()

We want to check for s_inode's existence, not inode's one
(inode is always valid in this function).

This takes care of the following entry from Dan's list:

fs/ncpfs/ioctl.c +445 __ncp_ioctl(180) warning: variable derefenced before check 'inode'
