I picked this up because it hasn't been merged for a year and the
original author didn't seem to react to that either..

The original driver change that was paired with this patch has
bitrotted, but this is still useful on its own (if only to reduce the
number of DT checker warnings in qcom/..)

No changes besides `b4 trailers -u && git commit --amend -s`
