Subject: [PATCH 4/6] VMCI: Fix "always true condition"
Date: Thu, 10 Jan 2013 15:41:41 -0800	[thread overview]
Message-ID: <1357861303-25903-4-git-send-email-dtor@vmware.com> (raw)
In-Reply-To: <1357861303-25903-1-git-send-email-dtor@vmware.com>

From: Andy King <acking@vmware.com>

vmci_send_datagram() returns an int, with negative values indicating failure.
But we store it locally in a u32, which makes comparison of >= 0 useless.
Fixed to use an int.
