Thanks for replying,
So I refers to the solution on ARM64 and sent my patch on January as below.

http://lists.infradead.org/pipermail/linux-arm-kernel/2021-January/628460.html

But I haven't got any replies on my patch. How can I get my patch reviewed
and submitted to the patch system?Should I resend a new patch to this maillist?
Thanks!
