Subject: [PATCH] iio: adc: Replace license text w/ SPDX identifier

From: Lucas Santos <[email protected]>

This patch removes all license boilerplate texts from the .c and .h
files at drivers/iio/adc/ and, instead, adds the proper SPDX license
identifiers.

Hi Lucas, Matheus,

Doing this as a large all at once patch may seem like a good idea, but...

Whilst it is now kernel policy (sort of) to use SPDX, that doesn't
correspond to converting all code without input from the original
authors.

As such, I am normally only happy to apply SPDX patches with an
ack from either the original author, or at least someone from the
company who holds the copyright.

I have expressed before that I actually consider these mostly
noise and so am not keen at all unless there is other work
being done on a particular driver.

So please split this up into at least separate patches
for each of the copyright holders, so they can provide an ACK
if they are happy with this change.

Some companies will for example want their legal departments to
do a review of whether SPDX is acceptable for their past contributions.
(lots won't care btw - but the potential is there).

+CC Linus Walleij as one of his files doesn't have a license...

A few other comments inline...

Thanks,

Jonathan

Oh great, contradictory license text. The first
part would normally imply GPL-2.0 and the second
is clearly GPL-2.0+

I'd leave this one be unless you can get input from the various
authors.

This one's mine so in a separate patch you can add.

Sorry about that. I am fine with GPL-2.0 or GPL-2.0+ on
any of "my" files. Feel free to add it with my Acked-by.

Yours,
