[alsa-devel] [PATCH] ASoC: make ops a pointer in 'struct snd_soc_dai'

Eric Miao eric.y.miao at gmail.com
Mon Mar 2 04:25:46 CET 2009


Considering the fact that most cpu_dai or codec_dai are using a same
'snd_soc_dai_ops' for several similar interfaces, 'ops' would be better
made a pointer instead, to make sharing easier and code a bit cleaner.

The patch below is rather preliminary since the asoc tree is being
actively developed, and this touches almost every piece of code,
(and possibly many others in development need to be changed as
well). Building of all codecs are OK, yet to every SoC, I didn't test
that.
