Apparently I had applied your previous version to my local tree, but I had
completely forgotten about it. So it has received quite some compile testing.

CONFIG_GEN_RTC is not enabled in any of the m68k defconfigs, so I think it's
been unused for a while.
CONFIG_RTC_DRV_GENERIC is modular, so I typically don't run-test it.
I just did that, and after fixing patch 1 to use IS_ENABLED() it worked fine
on ARAnyM.

I do not have a Q40, so I couldn't test that part.

Thanks!

Gr{oetje,eeting}s,
