ALSA: bebob: fix to processing in big-endian machine for sending cue

2015-04-19T08:10:10+00:00

commit a053fc318bc5d28cd25168c948255fd48a29ea26 upstream. Some M-Audio devices require to receive bootup command just after powering on, while codes in BeBoB driver doesn't work properly in big-endian machine because the command should be aligned by little-endian. This commit fixes this bug. This fix should go to stable kernel. Cc: Takayuki Shiroma Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai Signed-off-by: Greg Kroah-Hartman

ALSA: fireworks/bebob/dice/oxfw: make it possible to shutdown safely

2015-03-18T13:11:05+00:00

commit dec84316dd53c90e93b4ee849483bd4bd1e9a585 upstream. A part of these drivers, especially BeBoB driver, are programmed to wait some events. Thus the drivers should not destroy any data in .remove() context. This commit moves some destructors from 'struct fw_driver.remove()' to 'struct snd_card.private_free()' to shutdown safely.

ALSA: fireworks/bebob/dice/oxfw: allow stream destructor after releasing runtime

2015-03-18T13:11:05+00:00

commit d23c2cc4485d10f0cedfef99dd2961d9652b1b3f upstream. Currently stream destructor in each driver has a problem to be called in a context in which sound card object is released, because the destructors call amdtp_stream_pcm_abort() and touch PCM runtime data. The PCM runtime data is destroyed in application's context with snd_pcm_close(), on the other hand PCM substream data is destroyed after sound card object is released, in most case after all of ALSA character devices are released. When PCM runtime is destroyed and PCM substream is remained, amdtp_stream_pcm_abort() touches PCM runtime data and causes Null-pointer-dereference. This commit changes stream destructors and allows each driver to call it after releasing runtime. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai Signed-off-by: Greg Kroah-Hartman

ALSA: fireworks/bebob/dice/oxfw: add reference-counting for FireWire unit

2015-03-18T13:11:04+00:00

commit 12ed719291a953d443921f9cdb0ffee41066c340 upstream. Fireworks and Dice drivers try to touch instances of FireWire unit after sound card object is released, while references to the unit is decremented in .remove(). When unplugging during streaming, sound card object is released after .remove(), thus Fireworks and Dice drivers causes GPF or Null-pointer-dereferencing to application processes because an instance of FireWire unit was already released. This commit adds reference-counting for FireWire unit in drivers to allow them to touch an instance of FireWire unit after .remove(). In most case, any operations after .remove() may be failed safely. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai Signed-off-by: Greg Kroah-Hartman

ALSA: firewire-lib: remove rx_blocks_for_midi quirk

2015-01-16T21:50:45+00:00

There are several devices that expect to receive MIDI data only in the first eight data blocks of a packet. If the driver restricts the data rate to the allowed rate (as mandated by the specification, but not yet implemented by this driver), this happens naturally. Therefore, there is no reason to ever try to use more data packets with any device.

ALSA: bebob: Uninitialized id returned by saffirepro_both_clk_src_get

ALSA: bebob: fix wrong decoding of clock information for Terratec PHASE 88 Rack FW

2014-10-27T07:39:11+00:00

Terratec PHASE 88 rack fw has two registers for source of clock, one is for internal/external, and another is for wordclock/spdif for external. When clock source is internal, information in another register has no meaning. Thus it must be ignored, but current implementation decodes it. This causes over-indexing reference to labels.
