Merge tag 'spi-fix-v6.9-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi fixes from Mark Brown:
 "A few small fixes for v6.9,

  The core fix is for issues with reuse of a spi_message in the case
  where we've got queued messages (a relatively rare occurrence with
  modern code so it wasn't noticed in testing).

  We also avoid an issue with the Kunpeng driver by simply removing the
  debug interface that could trigger it, and address issues with
  confusing and corrupted output when printing the IP version of the AXI
  SPI engine"
