[SOLVED] ztdummy module


i am using the latest SVN release on kernel but when I try and modprobe ztdummy I get the following error :-

FATAL: Error inserting ztdummy (/lib/modules/ Unknown symbol in module, or unknown parameter (see dmesg)
FATAL: Error running install command for ztdummy

dmesg gives :-

ztdummy: Unknown symbol rtc_register
ztdummy: Unknown symbol rtc_unregister
ztdummy: Unknown symbol rtc_control

Any ideas ?

I didnt have RTC compiled as a module, and inserted.
