[PATCH 00/13] drm/vkms: Allow to configure device

Hi everyone,

In preparation for ConfigFS support, a flexible way to configure VKMS device(s)
is required.
This series adds the required APIs to create a configuration, the code changes
required to apply it and KUnit test validating the changes.

Louis Chauvet and I are working on ConfigFS support. In this series I tried to
merge his changes [1] with mine [2].
I kept his Signed-off-by to reflect that, even if I show up as the author of
some/most of the patches, this was a joint effort.

I'm still polishing the ConfigFS code [3] and its IGT tests [4] (connector
hot-add/remove bugs) but the IGT tests also exercise this series and can be used
for additional test coverage.

Best wishes,
José Expósito
