If you fix the issue, kindly add following tag as appropriate
Reported-by: kernel test robot <redacted>

All errors (new ones prefixed by >>):

   powerpc-linux-ld: drivers/rtc/rtc-sun6i.o: in function `sun6i_rtc_settime':

quoted

quoted

rtc-sun6i.c:(.text.sun6i_rtc_settime+0x218): undefined reference to `__udivdi3'  

For the records, I am using div_u64() now, which compiles fine in both
ARM and arm64.
Also found some subtle bugs with the types used in that function on the
way.

Thanks dear bot for also caring about those "lesser" architectures ;-)

Cheers,
Andre
