[alsa-devel] [PATCH] ASoC: SAMSUNG: Change s3c24xx directory name to samsung

Fri Jun 25 08:45:18 CEST 2010
This patch changes s3c24xx directory name to samsung.
(sound/soc/s3c24xx -> sound/soc/samsung)
Currently, the source files related to samsung SoCs(s3c24xx & s3c64xx)
are included in sound/soc/s3c24xx. It would be better to change s3c24xx
directory name to samsung, because s3c24xx directory will support
many board based on samsung SoCs(s5p, etc).
