According to i.MX27 Reference Manual (p 1593) TXBIT0 bit selects
whether the most significant or the less significant part of the
data word written to the FIFO is transmitted.
As DSP_A is the same as DSP_B with a data offset of 1 bit, it
doesn't make any sense to remove TXBIT0 bit here.

Recent enhancements in the bias management means that we might not be
in standby when the CODEC is idle and can have active widgets without
being in full power mode but the shutdown functionality assumes these
things. Add checks for the bias level at each stage so that we don't
do transitions other than the ON->PREPARE->STANDBY->OFF ones that the
drivers are expecting.

Current ak4642 driver had wrong dapm settings for headphone L/R.
If you select headphone L, and select R after that,
headphone L setting was removed by R settings.
This patch fixes it up.
It provides just "Headphone Enable" to user side

If an idle_bias_off device is in any state other than off then it is still
active for some reason (typically a low power function such as accessory
detection). This wasn't an issue when the feature was implemented as we
always went to _ON for any active function, subsequent power improvements
have changed things.
With the modern way of doing things we should overhaul the infrastructure
to allow devices to explicitly take references for these functions but
that's a much more invasive change and will require driver updates to
deploy, this will bring the framework into line with the existing driver
set before we do that work.

In wm2000_i2c_probe(), if we take the true branch in
"
ret = snd_soc_register_codec(&i2c->dev, &soc_codec_dev_wm2000,
NULL, 0);
if (ret != 0)
goto err_fw;
"
then we'll release_firmware(fw) at the 'err_fw' label. But we've already
done that just a few lines above. That's a use-after-free bug.
This patch restructures the code so that we always call
release_firmware(fw) before leaving the function, but only ever call
it once.
This means that we have to initialize 'fw' to NULL since some paths
may now end up calling it without having called request_firmware(),
but since request_firmware() deals gracefully with NULL pointers, we
are fine if we just NULL initialize it.

On a mx28evk board the following errors happens on mxs-sgtl5000 probe:
[ 0.660000] saif0_clk_set_rate: divider writing timeout
[ 0.670000] mxs-sgtl5000: probe of mxs-sgtl5000.0 failed with error -110
[ 0.670000] ALSA device list:
[ 0.680000] No soundcards found.
This timeout happens because clk_set_rate will result in writing to the DIV bits
of register HW_CLKCTRL_SAIF0 with the saif clock gated (CLKGATE bit set to one).
MX28 Reference states the following about CLKGATE:
"The DIV field can change ONLY when this clock gate bit field is low."
So call clk_prepare_enable prior to clk_set_rate to fix this problem.
After this change the mxs-saif driver can be correctly probed and audio is functional.

The two DACs for the front output and the surround/center/LFE/back
outputs are wired up out of phase, so when channels are duplicated,
their sound can cancel out each other and result in a weaker bass
response. To fix this, reverse the polarity of the neutron flow to
the front output.

For historical reasons, we allow module_param(bool) to take an int (or
an unsigned int). That's going away.
A few drivers really want an int: they set it to -1 and a parameter
will set it to 0 or 1. This sucks: reading them from sysfs will give
'Y' for both -1 and 1, but if we change it to an int, then the users
might be broken (if they did "param" instead of "param=1").
Use a new 'bint' parser for them.
(ntfs has a different problem: it needs an int for debug_msgs because
it's also exposed via sysctl.)
