Merge tag 'qcom-drivers-for-5.9-2' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers
Qualcomm driver additional updates for 5.9
This fixes a potential race condition with remoteprocs by not sending
acknowledgements until after registered drivers has processed the event.
It adds IPQ6018 support to the SMD RPM driver, fixes kerneldoc in the
same and converts the related DT binding to YAML.
Finally it fixes a compilation warning in the geni serial engine driver
when compiled without CONFIG_SERIAL_EARLYCON.
