ALSA: pcm_lib - cleanup & merge hw_ptr update functions

2010-01-07T14:47:38Z

Do general cleanup in snd_pcm_update_hw_ptr*() routines and merge them. The main change is hw_ptr_interrupt variable removal to simplify code logic. This variable can be computed directly from hw_ptr. Ensure that updated hw_ptr is not lower than previous one (it was possible with old code in some obscure situations when interrupt was delayed or the lowlevel driver returns wrong ring buffer position value).

[ALSA] Clean up PCM codes (take 2)

2006-03-31T15:58:59Z

- Clean up initialization and destruction of substream instance Now snd_pcm_open_substream() alone does most initialization jobs. Add pcm_release callback for cleaning up at snd_pcm_release_substream() - Tidy up PCM oss code Signed-off-by: Takashi Iwai
