Thank you for all your help! sorry for the delay, I was dragged away for a bit. Can you send these as separated patches per new functionality? Please use git format-patch to create the patches and try to clean them up so it is going to be easier to understand them. Can you check your mail client to wrap lines correctly? You have very long lines, for example: http://www.spinics.net/lists/alsa-devel/msg47793.html http://www.spinics.net/lists/alsa-devel/msg48199.html While they should be something like: http://www.spinics.net/lists/alsa-devel/msg47797.html Couple of comments, but it would be more beneficial to see a series... > ----------------------------------------------------------------------- > diff --git a/sound/soc/codecs/tlv320aic3x.c b/sound/soc/codecs/tlv320aic3x.c > index d7349bc..2c06e21 100644 > --- a/sound/soc/codecs/tlv320aic3x.c > +++ b/sound/soc/codecs/tlv320aic3x.c > @@ -89,6 +89,7 @@ struct aic3x_priv { > > /* Selects the micbias voltage */ > enum aic3x_micbias_voltage micbias_vg; > + unsigned char cached_gain[LINE1L_2_RADC_CTRL-MIC3LR_2_LADC_CTRL+1]; spaces around '+' '-' '=' See: Documentation/CodingStyle Also, make sure that tabs are not replaced by spaces and check the patch for long lines also.
