[PATCH] dt-bindings: mtd: Fix nand-controller.yaml license

[Miquel Raynal]

Binding files should be dual licensed, this file was writtent with the
idea in mind of following the rules, but the SPDX tag did not reflect
that correctly. Fix the tag so we are sure this file is licensed
correctly.

Yes, we do want dual license, but things converted from txt bindings 
need those authors' permission as the txt bindings are all implicitly 
GPLv2. That didn't happen here, so we kept the default implicit license. 
Looks like this case is all Bootlin authors for significant parts of the 
original txt binding, so you should be good on that part (assuming your 
employer agrees). Maxime did the schema, so need his permission too.

Note I have blanket permission on dual licensing from several companies 
for DT files. It would be nice to get the same from Bootlin.

I hereby allow the relicensing of all contributions from Bootlin
employees on Device Tree binding documents in the Linux kernel from
GPLv2 to GPLv2 or BSD-2-Clause.

Let me know if this statement is sufficient or if you need anything
more formal or specific.

Best regards,

Thomas Petazzoni

I'm not sure how redundant it is with what Thomas just said, but for
that patch and any license change from GPL to GPL+BSD-2-Clause:
