[alsa-devel] [PATCH] rate: Allow LGPL for libsamplerate commercial licensee

[Takashi Iwai]

alsa-plugins-rate is tagged with GPL just for following the license of
libsamplerate.  However, libsamplerate provides a commercial license
to allow it used with less restrictions.  In that case, we also don't
have to stick with GPL.  Instead, the code follows LGPL like other
plugin codes in this package.

If anyone sees a legal problem with this, please let me know.
I find it OK, but IANAL.
