DEBUG_ESRAM_SELFTEST is a bool Kconfig symbol. So esram_selftest.o will
never be part of a module, right?

There's some module specific boilerplate above. (Note that I'm not sure
whether KBUILD_MODNAME is module specific, sorry.) And the comment talks
about a module too.

Was your intention to make DEBUG_ESRAM_SELFTEST a tristate symbol?

Thanks,
