+/* send next IPC message in list */ +static void ipc_tx_next_msg(struct work_struct *work) +{ + struct snd_sof_ipc *ipc = + container_of(work, struct snd_sof_ipc, tx_kwork); + struct snd_sof_dev *sdev = ipc->sdev; + struct snd_sof_ipc_msg *msg; + unsigned long flags; + + spin_lock_irqsave(&sdev->ipc_lock, flags); + + /* send message if HW read and message in TX list */

s/HW read/HW ready/ I think.
