Subject: [PATCH 5/5] MdeModulePkg/IncompatiblePci: Use -1 to match any IDs
Date: Thu, 26 Jan 2017 14:09:27 +0800	[thread overview]
Message-ID: <20170126060927.352436-6-ruiyu.ni@intel.com> (raw)
In-Reply-To: <20170126060927.352436-1-ruiyu.ni@intel.com>

When the VendorId/DeviceId/RevisionId/SubsystemVendorId
/SubsystemDeviceId is (UINT64)-1, IncompatiblePciDeviceSupport
driver doesn't use it to match any IDs.
The patch fixes this bug.
Since PciBus driver always calls IncompatiblePciDeviceSupport
using IDs read from HW, (UINT64)-1 is never passed to this
driver.
