ASoC: rt5670: Set RT5670_IRQ_CTRL1 non volatile

2015-03-18T13:11:10+00:00

commit 850529249d7cce02e9bfae9476d09c8c51410d28 upstream.

RT5670_IRQ_CTRL1(0xbd) is a non volatile register. And we need to
restore its value after suspend/resume.

ASoC: omap-pcm: Correct dma mask

2015-03-18T13:11:10+00:00

commit d51199a83a2cf82a291d19ee852c44caa511427d upstream.

DMA_BIT_MASK of 64 is not valid dma address mask for OMAPs, it should be
set to 32.
The 64 was introduced by commit (in 2009):
a152ff24b978 ASoC: OMAP: Make DMA 64 aligned

But the dma_mask and coherent_dma_mask can not be used to specify alignment.

ALSA: oxfw: fix a condition and return code in start_stream()

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

commit f2b14c0bc510c6a8f67a4f36049deefe5d99a537 upstream.

The amdtp_stream_wait_callback() doesn't return minus value and
the return code is not for error code.

This commit fixes with a propper condition and an error code.

ALSA: hda - Disable runtime PM for Panther Point again

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

commit de5d0ad506cb10ab143e2ffb9def7607e3671f83 upstream.

This is essentially a partial revert of the commit [b1920c21102a:
'ALSA: hda - Enable runtime PM on Panther Point'].  There was a bug
report showing the HD-audio bus hang during runtime PM on HP Spectre
XT.

ALSA: hda: controller code - do not export static functions

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

commit 37ed398839fa3e0d2de77925097db7a370abb096 upstream.

It is a bad idea to export static functions. GCC for some platforms
shows errors like:

  error: __ksymtab_azx_get_response causes a section type conflict

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.

ALSA: firewire-lib: remove reference counting

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

commit c6f224dc20ad959175c2dfec70b5a61c6503a793 upstream.

AMDTP helper functions increment/decrement reference counter for an
instance of FireWire unit, while it's complicated for each driver to
process error state.

In previous commit, each driver has the role of reference counting. This
commit removes this role from the helper function.

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.
