Looks like this patch was re-sent about an hour later with a different
subject of ("tty: serial: qcom_geni_serial: Rectify UART suspend
mechanism") at <https://lkml.kernel.org/r/1539699060-3055-1-git-send-email-msavaliy@codeaurora.org>.
The subject of the later patch seems better.  I'll do my review there.
