soundwire: stream: fix bad unlock balance

2019-06-06T17:16:04+00:00

the msg lock is taken for multi-link cases only but released
unconditionally, leading to an unlock balance warning for single-link usages
This patch fixes this.

 =====================================
 WARNING: bad unlock balance detected!

 but there are no more locks to release!

soundwire: stream: fix out of boundary access on port properties

2019-05-27T05:04:12+00:00

Assigning local iterator to array element and using it again for
indexing would cross the array boundary.
Fix this by directly referring array element without using the local
variable.
