Hi Mark

soc_pcm_hw_params() does rollback when failed (A),

These patches replace commas by semicolons.  This was done using the
Coccinelle semantic patch (http://coccinelle.lip6.fr/) shown below.

This semantic patch ensures that commas inside for loop headers will not be

Coccinelle ensures that braces are added as needed when a single-statement

LIST_HEAD(x), *y;

The semantic patch could be improved to avoid these, but for the moment
they have been removed manually (2 occurrences).

Merge series "ASoC: sun8i-codec: support for AIF2 and AIF3" from Samuel Holland <samuel@sholland.org>:

This series adds support the other two AIFs present in the sun8i codec,
which can be used for codec2codec DAI links.

This series first fills out the DAI driver, removing assumptions that
were made for AIF1 (16 bits, 2 channels, certain clock inversions). Some
new logic is required to handle 3 DAIs and the ADC/DAC sharing the same
clock. Finally, it adds the new DAIs, and hooks them up with DAPM
widgets and routes per the hardware topology.

To minimize the number of patches in this series, related device tree
patches (increasing #sound-dai-cells, adding new DAI links) will be sent
separately.

Changes from v1:
  - Patches 1-8 from v1 (DAPM changes) were merged
  - Prefixed AIF constants with "SUN8I_CODEC_" [1, 7, 10, 16, 17]
  - Renamed variables in sun8i_codec_set_fmt for clarity [3]
  - Update sysclk->sysclk_rate if later calls to hw_params change the
    sample rate (thanks Chen-Yu for reminding me of this) [11]
  - Select COMMON_CLK for clk_set_rate_exclusive [12]
  - Add comments and hopefully clarify the clock protection logic [12]
  - Make the error message more concise and put it on one line [12]
  - Drop the "reg" variable holding SUN8I_AIF_CLK_CTRL(dai->id) [15]
  - Rename "div_reg" to "clk_reg" and adjust comments for clarity [17]
  - Improve the AIF2/AIF3 rate mismatch error message [17]
  - Minor grammar/wording fixes in commit messages [2, 4, 7, 8, 16, 17]
  - Added Maxime's Acked-by: [1-2, 4-9, 11, 13-14, 16]

ASoC: pcm5102a: Make codec selectable

The TI PCM5102A codec driver can be used with the generic sound card
drivers, so it should be selectable. For example, with the addition
of #sound-dai-cells = <0> property in DT, it can be used with simple/graph
card drivers.

ASoC: jz4740-i2s: Remove manual DMA peripheral ID assignment

All platforms that use the jz4740-i2s driver have been switched to
devicetree for a while now and the assignment of the DMA peripheral ID
is done in the devicetree.

It is no longer necessary to manually assign the peripheral ID in the
driver, so remove that. The DMA driver does not even look at the value
assigned in the driver anymore and always uses the value provided by the
devicetree.

And 1st Playback's necessary shutdown will not be called,

To avoid such case, this patch marks substream pointer when hw_params() was

ASoC: sun8i-codec: Automatically set the system sample rate

The sun8i codec has three clock/sample rate domains:
 - The AIF1 domain, with a sample rate equal to AIF1 LRCK
 - The AIF2 domain, with a sample rate equal to AIF2 LRCK
 - The SYSCLK domain, containing the ADC, DAC, and effects (AGC/DRC),
   with a sample rate given by a divisor from SYSCLK. The divisor is
   controlled by the AIF1_FS or AIF2_FS field in SYS_SR_CTRL, depending
   on if SYSCLK's source is AIF1CLK or AIF2CLK, respectively. The exact
   sample rate depends on if SYSCLK is running at 22.6 MHz or 24.6 MHz.

When an AIF (currently only AIF1) is active, the ADC and DAC should run
at that sample rate to avoid artifacting. Sample rate conversion is only
available when multiple AIFs are active and are routed to each other;
this means the sample rate conversion hardware usually cannot be used.

Only attach the event hook to the channel 0 AIF widgets, since we only
need one event when a DAI stream starts or stops. Channel 0 is always
brought up with a DAI stream, regardless of the number of channels in
the stream.

The ADC and DAC (along with their effects blocks) can be used even if
no AIFs are in use. In that case, we should select an appropriate sample
rate divisor, instead of keeping the last-used AIF sample rate.
44.1/48 kHz was chosen to balance audio quality and power consumption.

Since the sample rate is tied to active AIF paths, disabling pmdown_time
allows switching to the optimal sample rate immediately, instead of
after a 5 second delay.

i2c: core: Restore acpi_walk_dep_device_list() getting called after registering the ACPI i2c devs

Commit 21653a4181ff ("i2c: core: Call i2c_acpi_install_space_handler()
before i2c_acpi_register_devices()")'s intention was to only move the
acpi_install_address_space_handler() call to the point before where
the ACPI declared i2c-children of the adapter where instantiated by
i2c_acpi_register_devices().

But i2c_acpi_install_space_handler() had a call to
acpi_walk_dep_device_list() hidden (that is I missed it) at the end
of it, so as an unwanted side-effect now acpi_walk_dep_device_list()
was also being called before i2c_acpi_register_devices().

Move the acpi_walk_dep_device_list() call to the end of
i2c_acpi_register_devices(), so that it is once again called *after*
the i2c_client-s hanging of the adapter have been created.

This fixes the Microsoft Surface Go 2 hanging at boot.

random32: add a selftest for the prandom32 code

Given that this code is new, let's add a selftest for it as well.
It doesn't rely on fixed sets, instead it picks 1024 numbers and
verifies that they're not more correlated than desired.
