[PATCH] soundwire: stream: fix out of boundary access on port properties

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
