The scpi_clock driver can be built-in when CONFIG_COMPILE_TEST is set even when ARM_SCPI_PROTOCOL is a loadable module, and that results in a link error:
drivers/built-in.o: In function `scpi_clocks_probe': (.text+0x14453c): undefined reference to `get_scpi_ops' Using #if IS_REACHABLE() around the get_scpi_ops() declaration makes it build successfully in this case for compile-testing, but the effect is the same as when ARM_SCPI_PROTOCOL is disabled, as the code will not be used.
