Here and elsewhere in this series: why EXPORT_SYMBOL in this case?
This is only exported to rpmh.c, right?  You don't need EXPORT_SYMBOL
for that.  The Makefile puts rpmh.c and rpmh-rsc.c together in the
same "qcom_rpmh.o", and then even further the KConfig lists this as
bool so both are builtin to the kernel.
