Subject: [PATCH v1 07/10] xen/pt: Log xen_host_pci_get/set errors in MSI code.
Date: Thu, 2 Jul 2015 15:51:18 -0400 [thread overview]
Message-ID: <1435866681-18468-8-git-send-email-konrad.wilk@oracle.com> (raw)
In-Reply-To: <1435866681-18468-1-git-send-email-konrad.wilk@oracle.com>
We seem to only use these functions when de-activating the
MSI - so just log errors.
