Subject: [PATCH 1/3] xen/privcmd: return -ENOSYS for unimplemented IOCTLs
Date: Thu, 9 Feb 2017 14:17:44 +0000	[thread overview]
Message-ID: <1486649866-4869-2-git-send-email-paul.durrant@citrix.com> (raw)
In-Reply-To: <1486649866-4869-1-git-send-email-paul.durrant@citrix.com>

The code goes so far as to set the default return code to -ENOSYS but
then overrides this to -EINVAL in the switch() statement's default
case.

This patch removes this pointless and incorrect override.
