2011-06-16ALSA: 6fire - Fix signedness bugTorsten Schenk
Fixed remaining issues of the signedness bug discovered by Dan Carpenter. A check was remaining that tests if unsigned rt->rate is >= 0. Changed that so that rt->rate now consistently uses ARRAY_SIZE(rates) as invalid rate value and not -1.

2011-06-14ALSA: 6fire: Fix double-free bug in usb6fire_fw_ezusb_upload()Jesper Juhl
We have a double-free bug in sound/usb/6fire/firmware.c::usb6fire_fw_ezusb_upload(). We already call release_firmware(fw) on line 258, so when we then do it again after usb6fire_fw_ezusb_write() returns <0, we have a double-free. Easily fixed by just removing the last call to release_firmware(). Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-06-02ALSA: 6fire: Don't leak firmware in error pathJesper Juhl
One of the error paths in sound/usb/6fire/firmware.c::usb6fire_fw_ezusb_upload() neglects to free the memory allocated for the firmware before returning, thus leaking the memory. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-05-25ALSA: usb-audio: more control quirks for M-Audio FastTrack devicesDaniel Mack
Make use of the freshly introduced methods to re-use standard mixer handling and add some controls that are hidden but implemented in a standard conform way on M-Audio's FastTrack devices.

2011-05-25ALSA: usb-audio: add new quirk type QUIRK_AUDIO_STANDARD_MIXERDaniel Mack
This quirk type will let the driver assume that there is a standard mixer on a given interface, or that a specific mixer quirks will handle the device. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-05-25ALSA: usb-audio: export snd_usb_feature_unit_ctlDaniel Mack
In order to allow quirks functions to hook up to the standard feature unit op tables, this patch exports a pointer to the struct that is used internally. That way, all the code handling the control can be kept private, and external code can reference the symbol to re-use it.

2011-05-25ALSA: usb-audio: rework add_control_to_empty()Daniel Mack
This patch renames add_control_to_empty() to snd_usb_mixer_add_control() and exports it, so the quirks functions can make use of it. Also, as "struct mixer_build" is private to mixer.c, rewrite the function to take an argument of type "struct usb_mixer_interface" instead.

2011-04-28ALSA: usb-audio - Don't expose broken dB rangesTakashi Iwai
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. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-02-23ALSA: usb-audio: fix oops due to cleanup race when disconnectingTakashi Iwai
When a USB audio device is disconnected, snd_usb_audio_disconnect() kills all audio URBs. At the same time, the application, after being notified of the disconnection, might close the device, in which case ALSA calls the .hw_free callback, which should free the URBs too. Commit de1b8b93a0ba "[ALSA] Fix hang-up at disconnection of usb-audio" prevented snd_usb_hw_free() from freeing the URBs to avoid a hang that resulted from this race, but this introduced another race because the URB callbacks could now be executed after snd_usb_hw_free() has returned, and try to access already freed data. Fix the first race by introducing a mutex to serialize the disconnect callback and all PCM callbacks that manage URBs (hw_free and hw_params).

2011-02-14ALSA: usb-audio: add support for Native Instruments MK2 devicesDaniel Mack
The MK2 generation of Native Instruments' sound cards are in fact compliant to the USB audio standard of version 2 and other approved USB standards. However, they come up as vendor-specific device when first connected but can be told to come up with a new set of descriptors upon their next enumeration. The interfaces announced by the new descriptors will be handled by the kernel's class drivers. This is done by issuing a vendor specific device request and sending the device to reset. There are also some vendor-specific USB requests for some mixer elements that can't be exported in a standard compliant way. The driver now supports them with quirks handling mechanisms.
