Jyri Sarha	4a462ce084	ALSA: pcm: Allow 32 bit sample format in IEC958 channel status helper ... Treat 32 bit sample width as if it was 24 bits when generating IEC958 channel status bits. On some platforms 24 sample width is problematic and to get full 24 bit precision a 32 bit format, using only the 24 most significant bits, may have to be used.

Jyri Sarha	4a4436573a	ALSA: pcm: add IEC958 channel status helper for hw_params ... Add IEC958 channel status helper that gets the audio properties from snd_pcm_hw_params instead of snd_pcm_runtime. This is needed to produce the channel status bits already in audio stream configuration phase.

Russell King	9203dd016a	ALSA: pcm: add IEC958 channel status helper ... Add a helper to create the IEC958 channel status from an ALSA snd_pcm_runtime structure, taking account of the sample rate and sample size.
