I'm sorry for the confusion. It is a port of the original
Qualcomm/CodeAurora fix to the upstream driver.

See https://source.codeaurora.org/quic/la/kernel/msm-4.9/commit/?id=cc2e11eeb988964af72309f71b0fb21c11ed6ca9,

It's a port from QCI kernel, not a backport.
So I'd prefer for it to go into Linus's tree (and then be backported
to relevant -stable trees).
