6d4d41f011 ALSA: control: code refactoring for TLV request handler to user element set
User-defined element set registers own handler to get callbacks from TLV
ioctl handler. In the handler, execution path bifurcates depending on
requests from user space. At write request, container in given buffer is
registered to the element set, or replaced old TLV data. At the read
request, the registered data is copied to user space. The command request
is not allowed.  In current implementation, function of the handler
includes codes for the two cases.

This commit adds two helper functions for these cases so that readers can
easily get the above design.

450296f305 ALSA: control: code refactoring TLV ioctl handler
In a design of ALSA control core, execution path bifurcates depending on
target element. When a set with the target element has a handler, it's
called. Else, registered buffer is copied to user space. These two
operations are apparently different.  In current implementation, they're
on the same function with a condition statement. This makes it a bit hard
to understand conditions of each case.

This commit splits codes for these two cases.

30d8340b58 ALSA: control: obsolete user_ctl_lock
At a previous commit, concurrent requests for TLV data are maintained
exclusively between read requests and write/command requests. TLV
callback handlers in each driver has no risk from concurrent access for
reference/change.

In current implementation, 'struct snd_card' has a mutex to control
concurrent accesses to user-defined element sets. This commit obsoletes it.

4c8099e9ca ALSA: control: use counting semaphore as write lock for TLV write/command operations
In ALSA control interface, applications can execute three types of request
for Type-Length-Value (TLV) data to a set of elements; read, write and
command. In ALSA control core, all of the requests are handled within read
lock to a counting semaphore, therefore several processes can run to access
to the data at the same time for any purposes. This has an issue because
write and command requests have side effect to change state of a set of
elements for the TLV data. Concurrent access should be controlled for each
of reference/change case.

This commit uses the counting semaphore as read lock for TLV read requests,
while use it as write lock for TLV write/command requests. The state of a
set of elements for the TLV data is maintained exclusively between read
requests and write/command requests, or between write and command requests.

28a0989c99 ALSA: control: queue events within locking of controls_rwsem for TLV operation
Any control event is queued by a call of snd_ctl_notify(). This function
adds the event to each queue of opened file data corresponding to ALSA
control character devices. This function acquired two types of lock; a
counting semaphore for a list of the opened file data and a spinlock for
card data opened by the file. Typically, this function is called after
acquiring a counting semaphore for a list of elements in the card data.

In current implementation of TLV request handler, the function is called
after releasing the semaphore for a list of elements in the card data.
This release is not necessarily needed.

This commit removes the release to call the function within the critical
section so that later commits are simple.

 property API which was causing issues with the of-graph card.  This is
 fixed with some changes in the graph API itself as it seemed very likely

c0a480d1ac device property: Fix usecount for of_graph_get_port_parent()
Fix inconsistent use of of_graph_get_port_parent() where
asoc_simple_card_parse_graph_dai() does of_node_get() before
calling it while other callers do not. We can fix this by
not trashing the node passed to of_graph_get_port_parent().

Let's also make sure the callers have correct refcounts and remove
related incorrect of_node_put() calls for of_for_each_phandle
as that's done by of_phandle_iterator_next() except when
we break out of the loop early.

Let's fix both issues with a single patch to avoid kobject
refcounts getting messed up more if two patches are merged
separately.

Otherwise strange issues can happen caused by memory corruption
caused by too many kobject_del() calls such as:

BUG: sleeping function called from invalid context at

349d63c33a ASoC: Intel: Enabling ASRC for RT5663 codec on kabylake platform
This patch fixes the cracking noise in rt5663 headphones for kabylake platform
by calling rt5663_sel_asrc_clk_src() for RT5663_AD_STEREO_FILTER to set ASRC.

The ASRC function is for asynchronous MCLK and LRCK. For RT5663 ASRC should be
enabled to  support special i2s clock format like Intel's 100fs.
ASRC function will track i2s clock and generate a corresponding
system clock for codec. Calling this function helps select the clock source
for both RT5663_AD_STEREO_FILTER and RT5663_DA_STEREO_FILTER filters
which fixes the crackling sound.

7ad210ace5 ALSA: rme9652: fix format overflow warnings
gcc-7 warns about a possible sprintf format string overflow with a
temporary buffer that is used to print from another buffer of the same
size:

sound/pci/rme9652/hdspm.c: In function 'snd_hdspm_create_alsa_devices':
sound/pci/rme9652/hdspm.c:2123:17: error: ' MIDIoverMADI' directive writing 13 bytes into a region of size between 1 and 32 [-Werror=format-overflow=]

This extends the temporary buffer to twice the size, and changes
the code to use the safer snprintf() across the entire file.
The longer buffer is still necessary to avoid a format-truncation
warning.

There is no easy way to avoid the theoretical overflow in this case,
but using snprintf() will turn it into a harmless truncation.

The snd_pcm name is too long to fit into the card shortname

This changes the code to use length-checking functions that truncate
if necessary. The "[Thinkpad]" substring is now also part of the
snprintf(), as that could also overflow the buffer.

This changes the driver to use snprintf() so we truncate the string
instead of overflowing into the next field if that happens.

I decided to split out the second format string for the extra
DMA channel to keep the code simpler.

Open-coding "shortname" here gets us below the limit, and using
snprintf() is a good idea too.

610e1ae9b5 ALSA: fm801: Initialize chip after IRQ handler is registered
The commit b56fa687e0 ("ALSA: fm801: detect FM-only card earlier")
rearranged initialization calls, i.e. it makes snd_fm801_chip_init() to
be called before we register interrupt handler and set PCI bus
mastering.

Somehow it prevents FM801-AU to work properly. Thus, partially revert
initialization order changed by commit mentioned above.

This reverts commit f1013cdeee ("ASoC: ux500: drop platform DAI
assignments"), which seems to have been based on a misunderstanding and
prevents the platform driver callbacks from being made (e.g. to
preallocate DMA memory).

The real culprit for the warnings about attempts to create duplicate
procfs entries was commit 99b04f4c40 ("ASoC: add Component level
pcm_new/pcm_free" that broke PCM creation on systems that use more than
one platform component.

c641e5b207 ASoC: fix pcm-creation regression
This reverts commit 99b04f4c40 ("ASoC: add Component level
pcm_new/pcm_free"), which started calling the pcm_new callback for every
component in a *card* when creating a new pcm, something which does not
seem to make any sense.

This specifically led to memory leaks in systems with more than one
platform component and where DMA memory is allocated in the
platform-driver callback. For example, when both mcasp devices are being
used on an am335x board, DMA memory would be allocated twice for every
DAI link during probe.

When CONFIG_SND_VERBOSE_PROCFS was set this fortunately also led to
warnings such as:

WARNING: CPU: 0 PID: 565 at ../fs/proc/generic.c:346 proc_register+0x110/0x154
proc_dir_entry 'sub0/prealloc' already registered

Since there seems to be no users of the new component callbacks, and the
current implementation introduced a regression, let's revert the
offending commit for now.
