Hi lkp, (or is it ktr?)
This is sort of a shame-on-you post. As a robot, I hope that you
don't have any hard feelings about it. :)

When I (easily) reproduce this build error, I also see a Kconfig warning:
(or the same warning repeated 3 times)
WARNING: unmet direct dependencies detected for CMA

Selected by [m]:

This is the cause of the build errors.
You shouldn't omit Kconfig warnings from your reports.

Hi Randy, thanks for the input, below warning is helpful to identify
issues, we will add this to plan to show kconfig related warnings
in the report.
Thanks
