I received an email yesterday asking about the license of some code
found in FreeBSD to turn the fan on a Dell laptop on/off, the code in
question is shown below. I do not know exactly where in FreeBSD this
code lies, as I do not use FreeBSD. Neither do I want or should have to
go looking for it.
This code has been lifted verbatim out of drivers/char/i8k.c in Linux,
which in itself was a minor modification of code in
drivers/char/toshiba.c mdae by myself. This code dates back to January
1998, and was first included in Linux around 2.2.20. I am the original
author of this code, and it is clearly and only ever licensed under the
GPL. I must insist that it be removed forwith from FreeBSD.
JAB.
