#     Merge tag 'spi-fix-v5.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
#     
#     Pull spi fixes from Mark Brown:
#      "A few more bug fixes for SPI, both driver specific ones. The caching
#       in the Cadence driver is to avoid a deadlock trying to retrieve the
#       cached value later at runtime"
#     
#     * tag 'spi-fix-v5.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi:
#       spi: cadence: cache reference clock rate during probe
#       spi: fsl: Fix driver breakage when SPI_CS_HIGH is not set in spi->mode
