Subject: ASoC: msm: qdsp6v2: check audio client pointer before accessing
|
||
|
|
|
||
|
|
In the registered callback for q6asm, we are checking if
|
||
|
|
the audio client pointer is valid and also, dereferencing it
|
||
|
|
to get the session ID even though it could be invalid or expired.
|
||
|
|
Return and exit immediately if the audio client pointer is
|
||
|
|
invalid.
