I'm sorry, but I can't merge this as checkpatch doesn't approve of the
way you write the Co-developed-by, and I don't like it either - in
particular when looking at the 3rd patch,
As this is all from Qualcomm, please change this such that one person
(the author) certifies the origin of the patch (in accordance with DCO
1.1 bullet a). You can attribute the additional authors by writing
"Written in collaboration with Yingying Tang <and other names for the
3rd patch>" above the tags.
PS. Please run checkpatch before sending your patches.
Regards,
Bjorn
