Subject: [PATCH] xen/platform-pci: use define instead of literal number
Date: Mon, 14 Nov 2022 15:23:48 +0100 [thread overview]
Message-ID: <20221114142348.1499-1-jgross@suse.com> (raw)
Instead of "0x01" use the HVM_PARAM_CALLBACK_TYPE_PCI_INTX define from
the interface header in get_callback_via().
