From: Luiz Augusto von Dentz <redacted> This makes signalling priority 6 so it can push commands before the stream channel, without this the stream channel may be schedule first and cause the signalling commands to timeout while waiting a slot. --- v2: Return error if writes fails since that probably means the socket has been disconnected, also makes code setting socket to blocking a bit cleaner. v3: Remove cast as suggested by Marcel, make code setting stream fd to block a separate function. android/avdtp.c | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-)
