The description doesn't state why it fixes what: the patch is actually
a fix for the wrong ADC pickup in ca0132_capture_pcm_prepare() where
it assumes wrongly the multiple streams although the driver implements 
one stream per ADC.  (And, ca0132_capture_pcm_cleanup() already does
the right thing.)

Could you rephrase the patch description and resend?


thanks,

Takashi
