28b698b734 ASoC: pcm512x: Fix a double unlock in pcm512x_digital_mute()
We accidentally call mutex_unlock(&pcm512x->mutex); twice in a row.

I re-wrote the error handling to use "goto unlock;" instead of returning
directly.  Hopefully, it makes the code a little simpler.

906a9abc5d ASoC: Intel: Haswell/Broadwell: fix setting for .dynamic field
For some reason this field was set to zero when all other drivers use
.dynamic = 1 for front-ends. This change was tested on Dell XPS13 and
has no impact with the existing legacy driver. The SOF driver also works
with this change which enables it to override the fixed topology.

8a99255a50 perf stat: Fix endless wait for child process
We hit a 'perf stat' issue by using following script:

  #!/bin/bash

  sleep 1000 &
  exec perf stat -a -e cycles -I1000 -- sleep 5

Since "perf stat" is launched by exec, the "sleep 1000" would be the
child process of "perf stat". The wait4() call will not return because
it's waiting for the child process "sleep 1000" to end. So 'perf stat'
doesn't return even after 5s passes.

This patch lets 'perf stat' return when the specified child process ends
(in this case, the specified child process is "sleep 5").

Committer testing:

  # cat test.sh
  #!/bin/bash

  sleep 10 &
  exec perf stat -a -e cycles -I1000 -- sleep 5
  #

b9ced18acf ACPI: NUMA: Use correct type for printing addresses on i386-PAE
The addresses of NUMA nodes are not printed correctly on i386-PAE
which is misleading.

Here is a debian9-32bit with PAE in a QEMU guest having more than 4G
of memory:

qemu-system-i386 \
-hda /var/lib/libvirt/images/debian32.qcow2 \
-m 5G \
-enable-kvm \
-smp 10 \
-numa node,mem=512M,nodeid=0,cpus=0 \
-numa node,mem=512M,nodeid=1,cpus=1 \
-numa node,mem=512M,nodeid=2,cpus=2 \
-numa node,mem=512M,nodeid=3,cpus=3 \
-numa node,mem=512M,nodeid=4,cpus=4 \
-numa node,mem=512M,nodeid=5,cpus=5 \
-numa node,mem=512M,nodeid=6,cpus=6 \
-numa node,mem=512M,nodeid=7,cpus=7 \
-numa node,mem=512M,nodeid=8,cpus=8 \
-numa node,mem=512M,nodeid=9,cpus=9 \
-serial stdio

Because of the wrong value type, it prints as below:

[    0.021049] ACPI: SRAT Memory (0x0 length 0xa0000) in proximity domain 0 enabled
[    0.021740] ACPI: SRAT Memory (0x100000 length 0x1ff00000) in proximity domain 0 enabled

[    0.027802] ACPI: SRAT Memory (0x60000000 length 0x20000000) in proximity domain 9 enabled

The upper half of the start address of the NUMA domains between 6
and 9 inclusive was cut, so the printed values are incorrect.

Fix the value type, to get the correct values in the log as follows:

[    0.023698] ACPI: SRAT Memory (0x0 length 0xa0000) in proximity domain 0 enabled
[    0.024325] ACPI: SRAT Memory (0x100000 length 0x1ff00000) in proximity domain 0 enabled

This patch enables proper interrupts routing between UART module
in Exynos Audio SubSystem and the rest of the SoC. This routing is
completely transparent for UART device and CPU/GIC. UART driver requests
interrupts from the respective controller and enables/masks/handles it
by itself via standard methods.

There are boards (for example TM2), which use UART module in Exynos Audio
SubStem for communication with BlueTooth chip.

753a8d083e mfd: axp20x: Re-align MFD cell entries
In the axp20x driver, the various mfd_cell lists had varying amounts
of indentation, sometimes even within the same list. For the axp288,
there's no alignment at all.

Re-align the right hand side of the assignments with the least amount
of tabs possible. Also collapse the closing bracket and the opening
bracket of the next entry onto the same line for the axp288, to be
consistent with all the other mfd_cell lists.

This patch is whitespace change only. No functionality is modified.

ac4ca4b9f4 mfd: tps6586x: Handle interrupts on suspend
The tps6586x driver creates an irqchip that is used by its various child
devices for managing interrupts. The tps6586x-rtc device is one of its
children that uses the tps6586x irqchip. When using the tps6586x-rtc as
a wake-up device from suspend, the following is seen:

 PM: Syncing filesystems ... done.
 Freezing user space processes ... (elapsed 0.001 seconds) done.
 OOM killer disabled.
 Freezing remaining freezable tasks ... (elapsed 0.000 seconds) done.
 Disabling non-boot CPUs ...
 Entering suspend state LP1
 Enabling non-boot CPUs ...
 CPU1 is up
 tps6586x 3-0034: failed to read interrupt status
 tps6586x 3-0034: failed to read interrupt status

The reason why the tps6586x interrupt status cannot be read is because
the tps6586x interrupt is not masked during suspend and when the
tps6586x-rtc interrupt occurs, to wake-up the device, the interrupt is
seen before the i2c controller has been resumed in order to read the
tps6586x interrupt status.

The tps6586x-rtc driver sets it's interrupt as a wake-up source during
suspend, which gets propagated to the parent tps6586x interrupt.
However, the tps6586x-rtc driver cannot disable it's interrupt during
suspend otherwise we would never be woken up and so the tps6586x must
disable it's interrupt instead.

Prevent the tps6586x interrupt handler from executing on exiting suspend
before the i2c controller has been resumed by disabling the tps6586x
interrupt on entering suspend and re-enabling it on resuming from
suspend.

10628e3ecf mfd: ab8500-core: Return zero in get_register_interruptible()
This function is supposed to return zero on success or negative error
codes on error.  Unfortunately, there is a bug so it sometimes returns
non-zero, positive numbers on success.

I noticed this bug during review and I can't test it.  It does appear
that the return is sometimes propogated back to _regmap_read() where all
non-zero returns are treated as failure so this may affect run time.

IPv6 does not consider if the socket is bound to a device when binding
to an address. The result is that a socket can be bound to eth0 and then
bound to the address of eth1. If the device is a VRF, the result is that
a socket can only be bound to an address in the default VRF.

Resolve by considering the device if sk_bound_dev_if is set.
