ALSA: usb-audio: fix rate_list memory leak

2012-06-10T13:41:52+00:00

commit 5cd5d7c44990658df6ab49f6253c39617c53b03d upstream. The array of sample rates is reallocated every time when opening the PCM device, but was freed only once when unplugging the device.

ALSA: usb-audio - Avoid flood of frame-active debug messages

2012-01-26T00:13:09+00:00

commit 80c8a2a372599e604b04a9c568952fe39cd1851d upstream. With some buggy devices, the usb-audio driver may give "frame xxx active" kernel messages too often. Better to keep it as debug-only using snd_printdd(), and also add the rate-limit for avoiding floods.

ALSA: usb-audio - Fix the missing volume quirks at delayed init

2011-11-08T16:50:27+00:00

In the recent usb-audio driver, the initialization of volume ranges may be delayed when the device doesn't respond well at the probing time. But the volume quirks for certain devices are applied only in mixer_ctl_feature_info() thus only at the very first probe and will be missing when the volume range is initialized later. This patch moves the volume quirk code to be always called from the volume-range extraction (get_min_max()), so that the quirks are properly applied in the later init time.

ALSA: ua101: fix crash when unplugging

2011-11-06T10:21:42+00:00

If the device is unplugged while running, it is possible for a PCM device to be closed after the disconnect callback has returned. This means that kill_stream_urb() and disable_iso_interface() would try to access already-invalid or freed USB data structures. The function free_usb_related_resources() was intended to prevent this, but forgot to clear the affected variables.
