#     Pull spi fixes from Mark Brown:
#      "A bunch of fixes that came in for SPI during the merge window.
#     
#       Some from ST and others for their controller, one from Lukas for a
#       race between device addition and controller unregistration and one
#       from fix from Geert for the DT bindings which unbreaks validation"
