Since this is bool, but the dependent configurations are tristate,
configurations such as arm64:allmodconfig result in
CONFIG_QCOM_RPMPD=y
CONFIG_MFD_QCOM_RPM=m
CONFIG_QCOM_SMD_RPM=m
This in turn results in

Thanks for reporting this, the QCOM_RPMPD dependency on MFD_QCOM_RPM was removed
by a patch on top from Bjorn [1]. I have posted a fix now [2] to make QCOM_RPMPD
depend on QCOM_SMD_RPM=y
