Hello,
Looks good, but I have one comment, you can consider if you like it...
...
+static int omap_mcbsp2_st_set_mode(struct snd_kcontrol *kcontrol,
struct snd_ctl_elem_value *ucontrol)+{
- u8 value = ucontrol->value.integer.value[0];
- if (value == omap_st_is_enabled(1))
return 0;- if (value)
omap_st_enable(1);- else
omap_st_disable(1);- return 1;
+}
+static int omap_mcbsp2_st_get_mode(struct snd_kcontrol *kcontrol,
struct snd_ctl_elem_value *ucontrol)+{
- ucontrol->value.integer.value[0] = omap_st_is_enabled(1);
- return 0;
+}
+static int omap_mcbsp3_st_set_mode(struct snd_kcontrol *kcontrol,
struct snd_ctl_elem_value *ucontrol)+{
- u8 value = ucontrol->value.integer.value[0];
- if (value == omap_st_is_enabled(2))
return 0;- if (value)
omap_st_enable(2);- else
omap_st_disable(2);- return 1;
+}
+static int omap_mcbsp3_st_get_mode(struct snd_kcontrol *kcontrol,
struct snd_ctl_elem_value *ucontrol)+{
- ucontrol->value.integer.value[0] = omap_st_is_enabled(2);
- return 0;
+}
Instead of having these two set of function, I would have only one:
static int omap_mcbsp_st_put_mode(struct snd_kcontrol *kcontrol, struct snd_ctl_elem_value *ucontrol) { struct soc_mixer_control *mc = (struct soc_mixer_control *)kcontrol->private_value; u8 value = ucontrol->value.integer.value[0];
if (value == omap_st_is_enabled(mc->reg)) return 0;
if (value) omap_st_enable(mc->reg); else omap_st_disable(mc->reg);
return 1; }
static int omap_mcbsp_st_get_mode(struct snd_kcontrol *kcontrol, struct snd_ctl_elem_value *ucontrol) { struct soc_mixer_control *mc = (struct soc_mixer_control *)kcontrol->private_value;
ucontrol->value.integer.value[0] = omap_st_is_enabled(mc->reg);
return 0; }
Than
