This change resolves a new compile-time warning when built as a loadable module: WARNING: modpost: missing MODULE_LICENSE() in sound/soc/codecs/snd-soc-pcm512x-spi.o see include/linux/module.h for more information This adds the license as "GPL v2", which matches the header of the file. MODULE_DESCRIPTION and MODULE_AUTHOR are also added. Signed-off-by: Jesse Chan <jc@linux.com> Signed-off-by: Mark Brown <broonie@kernel.org>
