The ifdef guards in amdgpu_acpi_is_s0ix_supported(), however, test for CONFIG_PM_SLEEP which is defined like this: config PM_SLEEP def_bool y depends on SUSPEND || HIBERNATE_CALLBACKS and that randconfig has: # CONFIG_SUSPEND is not set CONFIG_HIBERNATE_CALLBACKS=y leading to the module export missing. Change the ifdeffery to depend directly on CONFIG_SUSPEND.
