Hrm, not good.

sound/pci/hda/patch_ca0132.c: In function ‘ca0132_playback_pcm_prepare’:
sound/pci/hda/patch_ca0132.c:2675:2: error: implicit declaration of function ‘ca0132_toggle_dac_format’ [-Werror=implicit-function-declaration]
  ca0132_toggle_dac_format(codec);
  ^

Please give a patch that really builds and works cleanly with the
upstream code!


thanks,

Takashi
