Hi Song,
Please clearly mark the title of the patch with V2.
[PATCH 1/2 V2] ...
(or I'm also happy with a cover letter that does the same though other
maintainers ask for every patch to be marked v2).
This makes it easy to quickly short the versions and check we are
looking at the latest.

A quick scan around their website suggests they are actually
"PNI Sensor Corporation"
I'm not sure how fussy we are on naming in here but probable best to be as specific
as possible.
