ALSA: hda - Disable runtime PM for Panther Point again

2015-02-25T06:53:31+00:00

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

2015-02-24T13:14:55+00:00

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: pcm: Don't leave PREPARED state after draining

2015-02-23T15:48:18+00:00

When a PCM draining is performed to an empty stream that has been
already in PREPARED state, the current code just ignores and leaves as
it is, although the drain is supposed to set all such streams to SETUP
state.  This patch covers that overlooked case.

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

2015-02-23T08:11:24+00:00

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

2015-02-23T08:11:16+00:00

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

2015-02-23T08:11:08+00:00

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

2015-02-23T08:10:38+00:00

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.

ALSA: hda - Add pin configs for ASUS mobo with IDT 92HD73XX codec

2015-02-23T07:46:04+00:00

BIOS doesn't seem to set up pins for 5.1 and the SPDIF out, so we need
to give explicitly here.

ALSA: firewire-lib: fix an unexpected byte sequence for micro sign

2015-02-23T07:46:03+00:00

The sign for microsecond (U+0085, MICRO SIGN) was encoded to '0x c2 b5'
by UTF-8 character encoding scheme. But the byte sequence was converted
to '0x c3 82 c2 b5' in a previous commit. As a result, the byte
sequence cannot represent microsecond sign in UTF-8 or ASCII. This
may confuse developers.

This commit replaces the sign to string expression with 'microseconds'
to purge superfluous troubles.
