I've pushed the patches to a branch to let the kbuild bot run through its
build tests again, and if I have extra time today I will try to
reproduce this and let you know the results.

Thanks,

Ah, Now I see.


Because you added "modpost:" prefix.



The previous error message:

ERROR: "adc_single" [arch/sh/boards/mach-hp6xx/hp6xx_apm.ko] undefined!


The new error message:

ERROR: modpost: "adc_single" [arch/sh/boards/mach-hp6xx/hp6xx_apm.ko] undefined!



So, the bot assumed it was a new error.

Nice catch! Hm, I suppose we need to let the LKP folks know about the
change in error message. CC'd LKP mailing list.
