Subject: [PATCH 2/2] tools: hv: fcopy: set 'error' in case an unknown operation was requested
Date: Mon, 17 Sep 2018 04:14:55 +0000	[thread overview]
Message-ID: <20180917041455.11455-2-kys@linuxonhyperv.com> (raw)
In-Reply-To: <20180917041455.11455-1-kys@linuxonhyperv.com>

From: Vitaly Kuznetsov <vkuznets@redhat.com>

'error' variable is left uninitialized in case we see an unknown operation.
As we don't immediately return and proceed to pwrite() we need to set it
to something, HV_E_FAIL sounds good enough.
