The user timer tu->qused counter may go to a negative value when
multiple concurrent reads are performed since both the check and the
decrement of tu->qused are done in two individual locked contexts.
This results in bogus read outs, and the endless loop in the
user-space side.
The fix is to move the decrement of the tu->qused counter into the
same spinlock context as the zero-check of the counter.

The i.MX51 datasheet says:
Chapter 56.1.2.4 I2S Mode
...
When I2S modes are entered (I2S master (01) or I2S slave (10)),
the following settings are recommended:
...
- TX Frame Rate should be 2 i.e. (STCCR[12:8] = 1)
- RX Frame Rate should be 2 i.e. (SRCCR[12:8] = 1)
Chapter 56.3.3.12 SSI Transmit and Receive Clock Control Registers (STCCR & SRCCR)
...
Bits 12-8 DC4-DC0
Frame Rate Divider Control. These bits are used to control the divide ratio
for the programmable frame rate dividers. The divide ratio works on the word
clock. In Normal mode, this ratio determines the word transfer rate.
In Network mode, this ratio sets the number of words per frame. The divide
ratio ranges from 1 to 32 in Normal mode and from 2 to 32 in Network mode.
In Normal mode, a divide ratio of 1 (DC=00000) provides continuous periodic
data word transfer. A bit-length frame sync must be used in this case.
Function fsl_ssi_hw_params() setup Normal mode for MONO output,
so with DC=0, SSI enters to continuous periodic data word transfer.
To fix this, setup DC for any I2S mode.
Patch has tested on custom board based on Digi CCMX-51 module (i.MX51).

vortex_wtdma_bufshift() function does calculate the page index
wrongly, first masking then shift, which always results in zero.
The proper computation is to first shift, then mask.

'commpage_bak' is allocated with 'sizeof(struct echoaudio)' bytes.
We then copy 'sizeof(struct comm_page)' bytes in it.
On my system, smatch complains because one is 2960 and the other is 3072.
This would result in memory corruption or a oops.

port for DMA access.
When using the CFG port only one serializer can be used per direction so
print error message and only configure the first serializer's offset.

Static checker warns:
Pointer 'hlink' returned from call to function 'snd_hdac_ext_bus_get_link'
at line may be NULL and will be dereferenced"
So we should always check the return of snd_hdac_ext_bus_get_link() before
referencing the link pointer

That is some different register for ALC255 and ALC256.
ALC256 can't fit with some ALC255 register.
This issue is cause from LDO output voltage control.
This patch is updated the right LDO register value.

Most users of IS_ERR_VALUE() in the kernel are wrong, as they
pass an 'int' into a function that takes an 'unsigned long'
argument. This happens to work because the type is sign-extended
on 64-bit architectures before it gets converted into an
unsigned type.
However, anything that passes an 'unsigned short' or 'unsigned int'
argument into IS_ERR_VALUE() is guaranteed to be broken, as are
8-bit integers and types that are wider than 'unsigned long'.
Andrzej Hajda has already fixed a lot of the worst abusers that
were causing actual bugs, but it would be nice to prevent any
users that are not passing 'unsigned long' arguments.
This patch changes all users of IS_ERR_VALUE() that I could find
on 32-bit ARM randconfig builds and x86 allmodconfig. For the
moment, this doesn't change the definition of IS_ERR_VALUE()
because there are probably still architecture specific users
elsewhere.
Almost all the warnings I got are for files that are better off
using 'if (err)' or 'if (err < 0)'.
The only legitimate user I could find that we get a warning for
is the (32-bit only) freescale fman driver, so I did not remove
the IS_ERR_VALUE() there but changed the type to 'unsigned long'.
For 9pfs, I just worked around one user whose calling conventions
are so obscure that I did not dare change the behavior.
I was using this definition for testing:
#define IS_ERR_VALUE(x) ((unsigned long*)NULL == (typeof (x)*)NULL && \
unlikely((unsigned long long)(x) >= (unsigned long long)(typeof(x))-MAX_ERRNO))
which ends up making all 16-bit or wider types work correctly with
the most plausible interpretation of what IS_ERR_VALUE() was supposed
to return according to its users, but also causes a compile-time
warning for any users that do not pass an 'unsigned long' argument.
I suggested this approach earlier this year, but back then we ended
up deciding to just fix the users that are obviously broken. After
the initial warning that caused me to get involved in the discussion
(fs/gfs2/dir.c) showed up again in the mainline kernel, Linus
asked me to send the whole thing again.

ASoC: Updates for v4.7 part 2
Really sorry about this late pull request. It looks like at the time I
sent my pull request for v4.7 there was some conflict or other issue
which caused my script to stop merging the ASoC branches at some point
after the HDMI changes.
It's all specific driver updates, including:
- New drivers for MAX98371 and TAS5720.
- SPI support for TLV320AIC32x4.
- TDM support for STI Uniperf IPs.
This code should all have been in -next prior to the merge window apart
from some fixes, it dropped out on the 18th.
