[PATCHv3 7/8] android/avdtp: Refactor local SEP list handling

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

 



From: Andrei Emeltchenko <andrei.emeltchenko@xxxxxxxxx>

In order to deduplicate similar code in android/ and profiles/ we need
to handle local SEP list outside of avdtp.c.
