From 6261f90bdb0b605ffb158717ec7a03b1753aded5 Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Sun, 4 Aug 2019 15:21:21 +0900 Subject: ALSA: firewire-lib: add a kernel API to stop a couple of AMDTP streams in AMDTP domain This commit adds a kernel API to stop a couple of isochronous contexts for AMDTP streams. The API is not protected with any lock primitive. Callers should use this with enough lock against concurrent access.
