Yeah. I was hoping someone would explain what's going on with the
driver.

Presumably there are some out-of-tree drivers that use the routines
provided by this driver?

I think rather than merging this patch, which keeps the code but makes
it completely useless, do you mind sending a patch to remove the whole
driver? Maybe that will get someone's attention.
