Subject: [PATCH] drm/doc: Custom Kconfig for KUnit is no longer needed

When built for UML, KUnit provides virtio/PCI, which means that the
DMA/IOMEM UML emulation needed by DRM is already present and does not
need to be manually added with --kconfig_add.

Use Fixes: tag for bugfix patches instead.

Can documentation update (when the referenced patch didn't touch the docs)
really be treated as a bugfix?
Or is it just a reference, validating the reasoning behind this patch?

I kind of agree; I'm not sure that a Fixes tag is really warranted here.

Thanks,

Thanks for the patch. This was in my ToDo list and I was waiting until
6fc3a8636a7b was merged in the DRM tree, but since you already fixed it
I can mark it as done.

Thanks!
