My bad, I repetedly ignored the error report received from the 'kernel
test robot' about this. Thanks for fixing.

For my eduction, why would the vchiq-mmal code not get build if
vchiq-core is set to M ? I mean, that configuration is indeed wrong,
as vchiq-mmal uses symbols from vchiq-core and I would expect that to
fail when building the kernel image, not have the other modules (as
bcm2835-camera) fail as a consequence when building modules.

If you noticed this from the same error notification I recevied it
might be fair to report:
Reported-by: kernel test robot <lkp@intel.com>
