ASoC: Optimize switch/case in magician.c
Use default to optimize the switch/case in magicial_playback_hw_params(), which also fixes the compile warnings below: sound/soc/pxa/magician.c:89: warning: 'acds' may be used uninitialized in this function sound/soc/pxa/magician.c:89: warning: 'acps' may be used uninitialized in this function Signed-off-by: Takashi Iwai <tiwai@suse.de>
