#     Merge tag 'spi-fix-v5.15-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
#     
#     Pull spi fixes from Mark BrownL
#      "This contains a couple of fixes, one fix for handling of zero length
#       transfers on Rockchip devices and a warning fix which will conflict
#       with a version you did but cleans up some extra unneeded forward
#       declarations as well which seems a bit neater"
