| Subject: soundwire: Initialize completion for defer messages |
| |
| From: Shreyas NC <shreyas.nc@intel.com> |
| |
| [ Upstream commit a306a0e4a5326269b6c78d136407f08433ab5ece ] |
| |
| Deferred messages are async messages used to synchronize |
| transitions mostly while doing a bank switch on multi links. |
| On successful transitions these messages are marked complete |
| and thereby confirming that all the buses performed bank switch |
| successfully. |
| |
| So, initialize the completion structure for the same. |
