In a rare combination of Kconfig settings, the 88pm860x-codec
module may be selected as a loadable module, while it's also being
used by the ttb-dkb code that is built-in, resulting in a link
error:
sound/built-in.o: In function `ttc_pm860x_init':
:(.text+0x3e888): undefined reference to `pm860x_hs_jack_detect'
:(.text+0x3e898): undefined reference to `pm860x_mic_jack_detect'
Changing ttb-tkb to a tristate option tells Kconfig that 88pm86x
actually needs to be built-in if ttc-dkb is also built-in.

The rt5677 codec has gained code that requires SPI to work correctly,
but there is no provision in Kconfig to prevent the driver from
being used when SPI is disabled or a loadable module, resulting
in this build error:
sound/built-in.o: In function `rt5677_spi_write':
:(.text+0xa7ba0): undefined reference to `spi_sync'
sound/built-in.o: In function `rt5677_spi_driver_init':

ERROR: "spi_register_driver" [sound/soc/codecs/snd-soc-rt5677-spi.ko] undefined!
This makes the SPI portion of the driver depend on the SPI subsystem,
and disables the function that uses SPI for firmware download if SPI
is disabled. The latter may not be the correct solution, but I could
not come up with a better one.

An earlier bug fix of mine made the SND_DM365_VOICE_CODEC symbol
tristate to avoid creating an undefined reference from the
davinci-vcif.c driver to the davinci_soc_platform_register
function that may be in a module.
However, this may now lead to a different error on randconfig
kernels:
"warning: SND_DM365_VOICE_CODEC creates inconsistent choice state"
This happens because we now have a choice statement with
one bool and one tristate option, and the latter might not
support being set to 'y' because of dependencies.
This new change turns the other option into 'tristate' as well,
which avoids the problem.

Currently only ice1712/juli.c deals with the PM and ak4114, so fix the

When ak4114 work calls its callback and the callback invokes
ak4114_reinit(), it stalls due to flush_delayed_work(). For avoiding
this, control the reentrance by introducing a refcount. Also
flush_delayed_work() is replaced with cancel_delayed_work_sync().
The exactly same bug is present in ak4113.c and fixed as well.

The PLL introduces jitter, which in turn introduces noice if used
to clock the DAC. Thus, avoid the PLL output, and use the PLL input
to drive the DAC clock, if possible.

forum post "PCM5142/PCM5242 DAC clock source" at the TI E2E community

Using the PLL in master mode requires using an external connection
between one of the GPIO pins (configured as PLL/4 output) and the
SCK pin. It also requires the external clock to be fed to some other
GPIO pin instead of the SCK pin.
This is described for the PCM5122 chip in the answers to the forum post
"PCM5122 DAC as I2S master troubles with PLL mode" at the TI E2E
community pages (1). The clocking functionality is also much better
described in the datasheet for the chip PCM5242, which seems to be
register compatible with PCM512x and PCM514x (which both have severely
lacking datasheets).

Add helper functions to allow drivers to specify several disjoint
ranges for a variable. In particular, there is a codec (PCM512x) that
has a hole in its supported range of rates, due to PLL and divider
restrictions.
This is like snd_pcm_hw_constraint_list(), but for ranges instead of

The current code deals with the stream start / stop solely via
line6_pcm_acquire() and line6_pcm_release(). This was (supposedly)
intended to avoid the races, but it doesn't work as expected. The
concurrent acquire and release calls can be performed without proper
protections, thus this might result in memory corruption.
Furthermore, we can't take a mutex to protect the whole function
because it can be called from the PCM trigger callback that is an
atomic context. Also spinlock isn't appropriate because the function
allocates with kmalloc with GFP_KERNEL. That is, these function just
lead to singular problems.
This is an attempt to reduce the existing races. First off, separate
both the stream buffer management and the stream URB management. The
former is protected via a newly introduced state_mutex while the
latter is protected via each line6_pcm_stream lock.
Secondly, the stream state are now managed in opened and running bit
flags of each line6_pcm_stream. Not only this a bit clearer than
previous combined bit flags, this also gives a better abstraction.
These rewrites allows us to make common hw_params and hw_free
callbacks for both playback and capture directions.
For the monitor and impulse operations, still line6_pcm_acquire() and
line6_pcm_release() are used. They call internally the corresponding
functions for both playback and capture streams with proper lock or
mutex. Unlike the previous versions, these function don't take the
bit masks but the only single type value. Also they are supposed to
be applied only as duplex operations.

Clearing prev_fsize in line6_pcm_acquire() is pretty racy.
This can be called at any time while the stream is being played.
Rather better to clear prev_fbuf and prev_fsize at the proper place
like the stream stop for capture, and just after copying the monitor /
impulse data inside the spinlock.

The impulse and monitor handling in submit_audio_out_urb() isn't
protected thus this can be racy with the capture stream handling.

(now the whole submit_audio_*_urb() are covered), and take the capture
stream lock additionally for the impulse and monitor handling part.
