I have run the `make dtbs_check` command, and did not notice the warning
message 'Missing generic name'. It shows lots of compatible failed messages.

Can not find the corresponding document.

Yes, I did run the ./scripts/checkpatch.pl and there were two warnings left.
- WARNING: added, moved or deleted file(s), does MAINTAINERS need updating?
- WARNING: line length of 104 exceeds 100 columns
I just ignore those warnings that Joel has informed me in the previous
mail loop.
