* ALSA: usb-audio: fix invalid length check for RME and other UAC 2 devicesClemens Ladisch2013-02-031-5/+12
| | | | | | | | | | | | | | | | | | | commit d56268fb108c7c21e19933588ca4d94652585183 upstream. Commit 23caaf19b11e (ALSA: usb-mixer: Add support for Audio Class v2.0) forgot to adjust the length check for UAC 2.0 feature unit descriptors. This would make the code abort on encountering a feature unit without per-channel controls, and thus prevented the driver to work with any device having such a unit, such as the RME Babyface or Fireface UCX.

* ALSA: usb-audio: Fix missing autopm for MIDI inputTakashi Iwai2013-01-111-42/+46
| | | | | | | | | | | | | | | | | | | | | commit f5f165418cabf2218eb466c0e94693b8b1aee88b upstream. The commit [88a8516a: ALSA: usbaudio: implement USB autosuspend] added the support of autopm for USB MIDI output, but it didn't take the MIDI input into account. This patch adds the following for fixing the autopm: - Manage the URB start at the first MIDI input stream open, instead of the time of instance creation - Move autopm code to the common substream_open() - Make snd_usbmidi_input_start/_stop() more robust and add the running state check Reviewd-by: Clemens Ladisch <clemens@ladisch.de> Tested-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* ALSA: ua101, usx2y: fix broken MIDI outputClemens Ladisch2012-12-031-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | commit e99ddfde6ae0dd2662bb40435696002b590e4057 upstream. Commit 88a8516a2128 (ALSA: usbaudio: implement USB autosuspend) added autosuspend code to all files making up the snd-usb-audio driver. However, midi.c is part of snd-usb-lib and is also used by other drivers, not all of which support autosuspend. Thus, calls to usb_autopm_get_interface() could fail, and this unexpected error would result in the MIDI output being completely unusable. Make it work by ignoring the error that is expected with drivers that do not support autosuspend.

* ALSA: usb-audio: Fix mutex deadlock at disconnectionTakashi Iwai2012-11-171-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 10e44239f67d0b6fb74006e61a7e883b8075247a upstream. The recent change for USB-audio disconnection race fixes introduced a mutex deadlock again. There is a circular dependency between chip->shutdown_rwsem and pcm->open_mutex, depicted like below, when a device is opened during the disconnection operation: A. snd_usb_audio_disconnect() -> card.c::register_mutex -> chip->shutdown_rwsem (write) -> snd_card_disconnect() -> pcm.c::register_mutex -> pcm->open_mutex B. snd_pcm_open() -> pcm->open_mutex -> snd_usb_pcm_open() -> chip->shutdown_rwsem (read) Since the chip->shutdown_rwsem protection in the case A is required only for turning on the chip->shutdown flag and it doesn't have to be taken for the whole operation, we can reduce its window in snd_usb_audio_disconnect().

* ALSA: usb-audio: Fix races at disconnectionTakashi Iwai2012-11-175-34/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | commit 978520b75f0a1ce82b17e1e8186417250de6d545 upstream. Close some races at disconnection of a USB audio device by adding the chip->shutdown_mutex and chip->shutdown check at appropriate places. The spots to put bandaids are: - PCM prepare, hw_params and hw_free - where the usb device is accessed for communication or get speed, in mixer.c and others; the device speed is now cached in subs->speed instead of accessing to chip->dev The accesses in PCM open and close don't need the mutex protection because these are already handled in the core PCM disconnection code. The autosuspend/autoresume codes are still uncovered by this patch because of possible mutex deadlocks. They'll be covered by the upcoming change to rwsem. Also the mixer codes are untouched, too. These will be fixed in another patch, too.

* ALSA: usb-audio - Fix the missing volume quirks at delayed initTakashi Iwai2011-11-211-50/+59
| | | | | | | | | | | | | | | | | | | commit dcaaf9f2c16b56f8bb316881fcd3f15c18fc71e7 upstream. 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.

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 Terratec Aureon 5.1 USB sound card support is broken since kernel 2.6.39. 2.6.39 introduced power management support for USB sound cards that added a probing flag in struct snd_usb_audio.

* ALSA: snd_usb_caiaq: track submitted output urbsDaniel Mack2011-08-292-4/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | commit da6094ea7d3c2295473d8f5134279307255d6ebf upstream. The snd_usb_caiaq driver currently assumes that output urbs are serviced in time and doesn't track when and whether they are given back by the USB core. That usually works fine, but due to temporary limitations of the XHCI stack, we faced that urbs were submitted more than once with this approach. As it's no good practice to fire and forget urbs anyway, this patch introduces a proper bit mask to track which requests have been submitted and given back. That alone however doesn't make the driver work in case the host controller is broken and doesn't give back urbs at all, and the output stream will stop once all pre-allocated output urbs are consumed. But it does prevent crashes of the controller stack in such cases. See http://bugzilla.kernel.org/show_bug.cgi?id=40702 for more details.

* ALSA: usb-audio - Fix missing mixer dB informationTakashi Iwai2011-08-291-1/+2
| | | | | | | | | | | | | | | | | commit 38b65190c6ab0be8ce7cff69e734ca5b5e7fa309 upstream. The recent fix for testing dB range at the mixer creation time seems to cause regressions in some devices. In such devices, reading the dB info at probing time gives an error, thus both dBmin and dBmax are still zero, and TLV flag isn't set although the later read of dB info succeeds. This patch adds a workaround for such a case by assuming that the later read will succeed. In future, a similar test should be performed in a case where a wrong dB range is seen even in the later read.

| * ALSA: usb-audio: remove invalid extra mixers for Komplete Audio 6Daniel Mack2011-05-183-19/+2
| | | | | | | | | | | | | | | | | | | | This was a flaw in the reading of the spec tables - Native Instrument's "Komplete Audio 6" device has no such extra controls. This patch also fixes the device name in two comments. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
| * ALSA: usb-audio: include format.h in format.cDaniel Mack2011-05-181-0/+1
| | | | | | | | | | | | | | | | Just in case a prototype changes, we'll be warned. This also fixes a sparse warning. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
| * ALSA: usb-audio: make hwc_debug a noop in case HW_CONST_DEBUG is not setDaniel Mack2011-05-181-1/+1
| | | | | | | | | | | | | | | | | | Just defining it to nothing is dangerous as it can alter the code execution flow, for example when used in as only function in a conditional code block. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
| * ALSA: usb-audio - Don't expose broken dB rangesTakashi Iwai2011-04-281-4/+6
| | | | | | | | | | | | | | | | | | Some crappy USB-audio devices give broken dB ranges, e.g. both min and max are 0dB. This confuses the volume control that prefers dB expression such as alsactl or PulseAudio. In such a case, it's much better not to expose the broken dB information.

| * ALSA: usb-audio: Add quirks for Audio Kontrol 6Daniel Mack2011-04-143-0/+24
| | | | | | | | | | | | | | | | | | | | | | This new device by Native Instruments is also compliant to the USB standard v2.0, but hides this detail at when connected. It needs the same boot quirks than other models, and also has two non-class-compliant mixer controls. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
