Hi Jiawei, 

 1.

    Do not send patches as attachments.

 2. A patch should only change one thing; you just need to modify the
    interrupt-related part there
 3. ./scripts/get_maintainer.pl your.patch .Use this script to get the
    maintainer. I noticed that you didn't obtain Greg and send it to him.

by the way, Can we collaborate on the WCH driver work? I can assist with
modifying and submitting the related drivers.

I am very interested in this matter.

thanks！
