Subject: [PATCH 4.8 17/37] KVM: PPC: BookE: Fix a sanity check
Date: Fri, 14 Oct 2016 14:27:03 +0200 [thread overview]
Message-ID: <20161014122552.181917130@linuxfoundation.org> (raw)
In-Reply-To: <20161014122549.411962735@linuxfoundation.org>
4.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@oracle.com>
commit ac0e89bb4744d3882ccd275f2416d9ce22f4e1e7 upstream.
We use logical negate where bitwise negate was intended. It means that
we never return -EINVAL here.
Fixes: ce11e48b7fdd ('KVM: PPC: E500: Add userspace debug stub support')
