From 3dc9ff388c9e832de9d902926aaadeb54c0755b1 Mon Sep 17 00:00:00 2001 From: Vidyakumar Athota Date: Mon, 3 Oct 2016 10:59:49 -0700 Subject: [PATCH] uapi: sound: add new ready packet type There is a chance that the user space can send commands to wdsp before transport layer is ready to use. Avoid this scenario by adding a new API which user space can invoke to check the status of the transport layer before sending any commands.
