Remove CoInstaller from INF
Windows 11 22H2 WHQL requires INF files pass "InfVerif /k", which highlights
several issues
- PnpLockdown=1 needs to be specified
- CoInstallers are no longer allowed
The CoInstaller has several functions that will need alternative solutions:
- The AllowUpdate mechanism is no longer possible
- The safety checks that ensure interface versionings remain compatible
Interface safety checks need to be handled by changes to child device bindings.
Also updates the INF bindings to require XenBus with CoInstaller removed to
maintain consistent CoInstaller removal versioning.

Remove REV from DeviceID
Driver upgrades use HardwareIDs (or CompatibleIDs) to match the child INF DDInstall
section (stored as matching device id), but use the DeviceID to generate the device
instance path. By keeping the device instance path the same over upgrades, the network
stack should identify this as an upgrade, rather than 'replacement hardware', and
not generate a new network connection, which would require network settings to be
copied from the existing network connection to the new network connection.
Note: Adds a strict requirement on child INF DDInstall sections, to specify the full
hardware ID (including revision) to guarantee interface versions are correctly supported

Correct return codes during racy destruction.
Errors in PnP retun codes found when testing under driver
verifier with mixed VM lifecycle operations. Under some
rare cases, it is possible to get more than one PnP
"remove-like" operation. This results in a PnP remove
operation being processed whilst the device is already
in the deleted state.
This patch fixes the immediate cause of the bugfixes,
by fixing the return code. Device destruction is
unchanged. Investigation into the root cause is still
ongoing.

CodeQL logs will be required for future WHQL submissions. Add a stage

Windows-Driver-Developer-Supplemental-Tools must be on the path defined
by the CODEQL_QUERY_SUITE environment variable (if defined), or under
the parent folder (if CODEQL_QUERY_SUITE variable is not defined)

MSBuild command line is not possible, so generate a batch file to wrap

This patch, rather than replacing calls to MmAllocatePagesForMdlEx() with

The patch instead passes MM_ALLOCATE_FULLY_REQUIRED, which arguably should
have always been passed for allocations larger than a single page. It also
