Subject: [PATCH 231/550] ASoC: Intel: Skylake: Send correct size in ipc header
|
|
for large config
|
|
|
|
To query information from FW we use "Large Config Get" message which accept
|
|
arguments in the form of extended params. So we need to send a TX message of
|
|
fixed size (8 bytes) to retrieve a large reply. Hence, IPC header should
|
|
reflect correct size of TX message for these messages.
