Subject[PATCH] drm: Simplify testing on UML with kunit.py
Date
DRM depends on IOMEM and DMA, introduce an additional Kconfig to pull in
IOMEM and DMA emulation on UML.
Since --kconfig_add usage is no longer needed, remove it from
documentation.

The configuration included in ``.kunitconfig`` should be as generic as
possible.
- ``CONFIG_VIRTIO_UML`` and ``CONFIG_UML_PCI_OVER_VIRTIO`` are not
