ASoC: Fixes for v3.16
A bigger batch of changes than I would like as I didn't send any for a
few weeks without noticing how many had built up. They are almost all
driver specific though, larger changes are:
- Fixes to the newly added Baytrail/MAX98090 which look like some QA
was missed on the microphone detection.
- Deletion of some erroniously listed audio formats for Haswell.
- Fix debugfs creation in the core so that we don't try to generate
multiple directories with the same name, relatively large textually
but simple to inspect by eye and test.
- A couple of bugfixes for the rcar driver one of which which involves
a bit of code motion to move initailisation of some hardware out of
common paths into device specific ones.
- Ensure both channels are powered up for mono outputs on Arizona
devices, involving some simple data tables listing the outputs and a
loop over them.
- A couple of fixes to save and restore information on suspended and
idle Samsung I2S controllers.

ASoC: Fixes for v3.16
Quite a few build coverage fixes in here among the usual small driver
fixes includling the sigmadsp change from Lars - moving the driver to
separate modules per bus (which is basically just code motion) avoids
issues with some combinations of buses being enabled.

Since we pass the port number through file private data for debugfs we cast
it to and from a pointer so use uintptr_t in order to ensure that the
types are compatible, avoiding warnings on 64 bit platforms where pointers
are 64 bit and unsigned integers 32 bit.

The patch 3117bb3109dc: "ASoC: fsl_asrc: Add ASRC ASoC CPU DAI and
platform drivers" from Jul 29, 2014, leads to the following Smatch
complaint:
sound/soc/fsl/fsl_asrc_dma.c:304 fsl_asrc_dma_shutdown()
warn: variable dereferenced before check 'pair' (see line 302)
sound/soc/fsl/fsl_asrc_dma.c
301 struct fsl_asrc_pair *pair = runtime->private_data;
302 struct fsl_asrc *asrc_priv = pair->asrc_priv;
^^^^^^^^^^^^^^^
Dereference.
303
304 if (pair && asrc_priv->pair[pair->index] == pair)
^^^^
Check.
305 asrc_priv->pair[pair->index] = NULL;
306
So we just let the driver check pair before using it.

Negating ADAU1977_BLOCK_POWER_SAI_LDO_EN creates an unsigned long constant
with all bits set which on 64 bit architectures needs to be truncated to
an unsigned int, generating a warning. Add an explicit cast since we know
this is OK.

- An off-by-one entry error in the Keystone LPAE setup code.
Fixes include:
- ensuring that the identity mapping for LPAE does not remove the
kernel image from the identity map.
- preventing userspace from trapping into kgdb.
- fixing a preemption issue in the Intel iwmmxt code.
- fixing a build error with nommu.

- Adding a note about which areas of memory are expected to be
accessible while the identity mapping tables are in place"

The kgdb breakpoint hooks (kgdb_brk_fn and kgdb_compiled_brk_fn)
should only be entered when a kgdb break instruction is executed
from the kernel. Otherwise, if kgdb is enabled, a userspace program
can cause the kernel to drop into the debugger by executing either
KGDB_BREAKINST or KGDB_COMPILED_BREAK.

Add a note about the usage of the identity mapping; we do not support
accesses outside of the identity map region and kernel image while a
CPU is using the identity map. This is because the identity mapping
may overwrite vmalloc space, IO mappings, the vectors pages, etc.

nr_dirty is updated without locking, causing it to drift so that it is
non-zero (either a small positive integer, or a very large one when an
underflow occurs) even when there are no actual dirty blocks. This was
due to a race between the workqueue and map function accessing nr_dirty
in parallel without proper protection.
People were seeing under runs due to a race on increment/decrement of
nr_dirty, see: https://lkml.org/lkml/2014/6/3/648
Fix this by using an atomic_t for nr_dirty.

1d3d4437eae1 ("vmscan: per-node deferred work") added a flags field to
struct shrinker assuming that all shrinkers were zero filled. The dm
bufio shrinker is not zero filled, which leaves arbitrary kmalloc() data
in flags. So far the only defined flags bit is SHRINKER_NUMA_AWARE.
But there are proposed patches which add other bits to shrinker.flags
(e.g. memcg awareness).
Rather than simply initializing the shrinker, this patch uses kzalloc()
when allocating the dm_bufio_client to ensure that the embedded shrinker
and any other similar structures are zeroed.
This fixes theoretical over aggressive shrinking of dm bufio objects.
If the uninitialized dm_bufio_client.shrinker.flags contains
SHRINKER_NUMA_AWARE then shrink_slab() would call the dm shrinker for
each numa node rather than just once. This has been broken since 3.12.

Fix the problem by using printk_deferred() which does not call into the

The direct-io.c rewrite to use the iov_iter infrastructure stopped updating
the size field in struct dio_submit, and thus rendered the check for
allowing asynchronous completions to always return false. Fix this by
comparing it to the count of bytes in the iov_iter instead.

In current R-Car rsnd driver,
the SND_SOC_DAIFMT_xB_xF flags are used to HW default behavior,
but, it should be used to specific format.
The waveforms of LEFT_J/RIGHT_J format with
SND_SOC_DAIFMT_NB_NF flag will be
started from "falling edge" without this patch.
But, it should be started from "rising edge".

DPCM needs extra dapm routes in the machine driver to route audio
between Front-End and Back-End. In order to differ the stream names
in the route map from CODECs, we here add specific stream names to
SSI driver so that we can implement ASRC via DPCM to it.

(ASoC: rsnd: add DVC support) added DVC support,
and it added pcm_new callback feature for it.
Then it called all DAI's pcm_new callback, and it was wrong.
This patch fixup it and call correct callback.

R-Car sound uses Audio Local Bus which uses Lch/Rch format.
This bus is used if driver uses BUSIF.
But sound data is written as Rch/Lch format in register.
This means Rch <-> Lch will be inverted.
SSIU :: BUSIF_DALIGN is used to controlling data format.
