Hmm, I'm getting this from checkpatch.pl --strict:

WARNING: Missing Signed-off-by: line by nominal patch author 'gtk_ruiwang <gtk_ruiwang@...iatek.com>'

Rather than sending this from 'gtk_ruiwang@...iatek.com', can you send this from
'Rui Wang <gtk_ruiwang@...iatek.com>'?

Then the two are the same.

Regards,
