Re: [PATCH 2/3] m68k: mac: use time64_t in RTC handling

[kbuild test robot]

Hi Arnd,

I love your patch! Yet something to improve:

[auto build test ERROR on powerpc/next]
[also build test ERROR on v4.18-rc1 next-20180618]
[cannot apply to m68k/for-next]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
