Modified files:
sys/dev/sound/usb uaudio.c
Log:
Provide hint / tunable for possible asynchronous USB execution. Async
execution should help us avoiding potential deadlock and illegal locking
while sleeping in various mixer -> usb calls. To enable it, use
hint.uaudio.%d.async="1" or sysctl dev.uaudio.%d.async=1. Default is
disable, to remain compatible with old behaviour (with slight risk of
potential deadlock).
