I think this is just another build failure that was hidden before my patch,
not caused by my patch.

That's an m68knommu kernel build with CONFIG_RTC_DRV_GENERIC=y,
I guess?

Correct, the  .config file is linked in the original report, just double-checked
that. More importantly, it's a nommu M68KCLASSIC (dragonball) config,
so the existing #ifdef CONFIG_M68KCLASSIC check in
arch/m68k/kernel/time.c is insufficient.

Sorry, the original report email was delayed by 9 hours, so I
got your response first.

Yeah, need to fix that, one day....

Hi Arnd,

Sorry for the inconvenience, we have added it to the ignore list.
