[libcamera-devel] [PATCH/RFC 00/11] Improve license information

[Laurent Pinchart]

Hello,

The REUSE specification [1] defines a standardized method for declaring
copyright and licensing information, based on SPDX. It comes with a
compliance tool that can check for compliance and produce reports, as
well as licensing information to generate packages.

libcamera already uses SPDX tags to specify license information, but we
haven't been using them very consistently, as shown by the "reuse lint"
tool. This series is an initial step towards REUSE compliance, and fixes
a few real issues.

I've marked the patches as RFC as it's not clear to me how far we need
to go. Adding an SPDX header to include/linux/README, for instance,
seems overkill to me. I'm also not sure what license to pick for
meson.build files. Comments are more than welcome.
