do_kernel_configcheck error after upgrading to release 2.10.0-rc1

[Heyi Guo]

Hi all,

After upgrading to openbmc 2.10.0-rc1, I got below error when building 
linux-aspeed:

ERROR: linux-aspeed-5.10.36+gitAUTOINC+992ac74129-r0 
do_kernel_configcheck: Error executing a python function in 
exec_python_func() autogenerated:

The stack trace of python calls that resulted in this exception/failure was:

ERROR: Task

failed with exit code '1'

It seems no one creates the parent directory "meta/cfg" before trying to 
create the file "invalid.txt". The error could be got around by manually 
creating meta/cfg under the specific directory.

Is it a yocto bug or did I miss something?

Thanks,

Heyi
