There's little point in providing partial and ancient information about the struct_mutex. Some drivers are using it, new ones should not.
As-it this only provides for confusion.

I think a doc patch to add a big warning for drm_device.struct_mutex would also be good. The current text is kinda unhelpful.
Would something like this be enough?
