Hi Roman and Andrew.
That error comes from the original patch-set of the driver, where a
there was missing "select DMA_SHARED_BUFFER" in Kconfig. So for
certain configurations, the build would fail.
This is already fixed in the current char-misc-next tree of gkh.

Thanks,
Oded

Hi Oded!


Thank you for sharing this information!


Tbh, I was surprised that the kbuild test robot did cc Andrew and others, as it's my private repo,

and I didn't send these patches publicly yet. Anyway, thank you for looking into the problem.


Thanks!

Roman
