Pull spi fix from Mark Brown:
"One last minute fix for v5.9 which has been causing crashes in test
systems with the fsl-dspi driver when they hit deferred probe (and
which I probably let cook in next a bit longer than is ideal).
And an update to MAINTAINERS reflecting Serge's extensive and
detailed recent work on the DesignWare driver"
* tag 'spi-fix-v5.9-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi:
