This looks basically OK but there's a *lot* of weird coding style issues in here. It's really all that, nothing too serious that I noticed - I've pointed out some of the patterns below not every individual issue.
- for (i = 0; i < ARRAY_SIZE(mic_gain_table); i++) {
if ((mic_gain_table[i].dgain == dgain_val)&& (mic_gain_table[i].scale == scale_val))ucontrol->value.integer.value[0] = i;- }
This indentation is really weird, why is the && aligned with the if?
- snd_soc_update_bits(codec, PDMIC_DSPR1,
PDMIC_DSPR1_OFFSET_MASK,(u32)(dd->pdata->mic_offset << PDMIC_DSPR1_OFFSET_SHIFT));
These are weird too, I'd expect the second line to be part of the first.
+static struct regmap *atmel_pdmic_codec_get_remap(struct device *dev) +{
- return dev_get_regmap(dev, NULL);
+}
This is (or should be) the default in the core.
- if ((fs < rate_min) || (fs > rate_max)) {
dev_err(codec->dev,"sample rate is %dHz, min rate is %dHz, max rate is %dHz\n",fs, rate_min, rate_max);
This too, alignment after the (.
- if (bits == 16)
dspr0_val = (PDMIC_DSPR0_SIZE_16_BITS<< PDMIC_DSPR0_SIZE_SHIFT);- else if (bits == 32)
dspr0_val = (PDMIC_DSPR0_SIZE_32_BITS<< PDMIC_DSPR0_SIZE_SHIFT);- else
return -EINVAL;
This looks like it should be a switch statement.
