• /* clock inversion */
• switch (fmt & SND_SOC_DAIFMT_INV_MASK) {
• case SND_SOC_DAIFMT_NB_NF:

• break;
  

• case SND_SOC_DAIFMT_IB_IF:

• break;
  

• case SND_SOC_DAIFMT_IB_NF:

• break;
  

• case SND_SOC_DAIFMT_NB_IF:

• break;
  

• default:

• break;
  

• }

This switch does nothing. Remove it?

Ok, I will remove it
