  here is fixes for:

   - vt unicode buffer corruption fix

   - imx serial driver fixes, again

   - port suspend fix

   - 8250_dw driver fix

   - fsl_lpuart driver fix

   - revert for the qcom_geni_serial driver to fix a reported regression

  All of these have been in linux-next with no reported issues"
