Subject: [PATCH] libi2c: Mention the correct license in source files
|
|
|
d3fc66f |
|
|
|
d3fc66f |
The libi2c library is released under the LGPL, not GPL, as explained
|
|
|
d3fc66f |
in the README file and documented in lib/Module.mk. Thanks to
|
|
|
d3fc66f |
Aurelien Jarno for pointing out the inconsistency.
|
|
|

|

A little bit of history:
|
|
|
d3fc66f |
|
|
|
d3fc66f |
The code started its life two decades ago as part of the lm-sensors
|
|
|
d3fc66f |
project, which was released as a whole under the GPL originally,
|
|
|
d3fc66f |
including the library part (libsensors).
|
|
|
d3fc66f |
|
|
|
d3fc66f |
In 2007, I decided to split the i2c tools, which are not specific
|
|
|
d3fc66f |
to sensor devices, to a separate package.
|
|
|
d3fc66f |
|
|
|
d3fc66f |
In 2009, as I was working on lm-sensors v3, I contacted all the
|
|
|
d3fc66f |
original authors to get their approval to release the upcoming and all
|
|
|
d3fc66f |
future versions of libsensors as LGPL instead, to allow wider
|
|
|
d3fc66f |
adoption. The proposal was accepted by all original authors.
|
|
|
d3fc66f |
|
|
|
d3fc66f |
In 2012, I decided to turn the inlined i2c_smbus_* helper functions
|
|
|
d3fc66f |
into a proper library, with the intent to release it under the LGPL,
|
|
|
d3fc66f |
as is the common practice for libraries. As the authors of this code
|
|
|
d3fc66f |
is a subset of the authors of libsensors, I assumed their agreement
|
|
|
d3fc66f |
for libsensors could be extended to libi2c as well. This is the
|
|
|
d3fc66f |
reason why LGPL is mentioned in README and lib/Module.mk.
|
|
|
d3fc66f |
|
|
|
d3fc66f |
Unfortunately, when working on the library code itself, I forgot to
|
|
|
d3fc66f |
update the comments in the source files. Let's fix them now.
