Subject: [PATCH 2/2] ext4 crypto: fix some error handling
Date: Mon, 22 May 2017 16:37:52 -0700	[thread overview]
Message-ID: <20170522233752.109220-2-ebiggers3@gmail.com> (raw)
In-Reply-To: <20170522233752.109220-1-ebiggers3@gmail.com>

From: Dan Carpenter <dan.carpenter@oracle.com>

commit 4762cc3fbbd89e5fd316d6e4d3244a8984444f8d upstream.  Please apply
to 4.4-stable.

We should be testing for -ENOMEM but the minus sign is missing.

Fixes: c9af28fdd449 ('ext4 crypto: don't let data integrity writebacks fail with ENOMEM')
