[Leilk Liu]

From: "leilk.liu" <leilk.liu@mediatek.com>

Given that these files have been licensed under the GPL only since 2015,
all changes contributed to it have only been licensed under the GPL as
well, so have you gotten approval for all of the contributors for this
change?

Can you please get your lawyer to also sign off on this license change
patch, so that we know that you have their approval for this incase
there are questions about it in the future?

thanks,

This is the reason that I sent this patch to ask for ACKs from all
contributors (who are all in the To mail-list) for these files.

I need to use the code in other projects that is not with GPL-2.0.
Also, the license change is approved by Mediatek supervisor.

That wasn't obvious :)

But given that many of the contributors here do not actually own the
copyrights of their contributions, how can you be sure that the real
owners are agreeing to this?  That requires something much more "legal"
than just an "ack" on a patch.  Please work with your corporate lawyers
for how to do this correctly.

What project needs this code that you can not just base it off of your
original contribution instead?  That would not require any license
change of the kernel files, right?  Wouldn't that be easier than trying
to retain this license change over time as you will not be taking the
changes here into another project as well.

Great, get them to also sign-off on the patch please, along with your
lawyers, so that we know all is done correctly.
