Hi Yuli,

When Thomas pointed out the "Signed-off-by chain is invalid" in v2:

https://lore.kernel.org/all/87zfpx4a0q.ffs@tglx/T/#mdc19b00c10177f3add9deaf505211bf8b3ec7110

I think it meant you either need to have a Co-developed-by for Zelong Xiang,
or you should remove his/her SoB.  The reason is the patch is from you, but
not Zelong.

The SoB chain needs to reflect the chronological history of this patch.  E.g.,
the SoB chain:

	From: You
	Co-developed-by: Zelong
	Signed-off-by: Zelong
	Signed-off-by: You

.. means the patch was originally generated by you, but Zelong also
participated in developing this patch before you finally signed off it.

For this one line code change patch, it doesn't make a lot sense to have
multiple developers, so I think you can just remove Zelong's SoB.
