This set of changes are fixing various section mismatch warnings which
look to be completely valid. Primerily, those which are fixed are those
which can cause oopses by manipulation of driver binding via sysfs. For
example: calling code marked __init from driver probe __devinit
functions.
Some of these changes will be reworked at the next merge window when the
underlying reasons are sorted out. In the mean time, I think it's
important to have this fixed for correctness.
Also included in this set are fixes to various error messages in OMAP -
including making them gramatically correct, fixing a few spelling
errors, and more importantly, making them greppable by unwrapping them.
Tony Lindgren has acked all these patches, put them out for testing a
week ago, and I've tested them on the platforms I have.

Some code - especially the crypto layer - wants to use the x86
FP/MMX/AVX register set in what may be interrupt (typically softirq)
context.
That *can* be ok, but the tests for when it was ok were somewhat
suspect. We cannot touch the thread-specific status bits either, so
we'd better check that we're not going to try to save FP state or
anything like that.
Now, it may be that the TS bit is always cleared *before* we set the
USEDFPU bit (and only set when we had already cleared the USEDFP
before), so the TS bit test may actually have been sufficient, but it
certainly was not obviously so.
So this explicitly verifies that we will not touch the TS_USEDFPU bit,
and adds a few related sanity-checks. Because it seems that somehow
AES-NI is corrupting user FP state. The cause is not clear, and this
patch doesn't fix it, but while debugging it I really wanted the code to
be more obviously correct and robust.

Per ./Documentation/CodingStyle, goto statements are acceptable for the
centralized exiting of functions when there are multiple exit points which
share common work such as cleanup. When no common work is required for
multiple exit points, the function should just return at these exit points
instead of doing an unnecessary jump to a centralized return. This patch
cleans up the inappropriate use of goto statements, and removes unnecessary
variables (or move to a smaller scope) where possible as a result of the
cleanups.

Merged back the fix for Acer Aspire 6935 with ALC889 codec.
The fix commit was based on 3.2 kernel so that it can be applied to
stable kernel cleanly.
Since 3.2 kernel, the driver starts trying to assign the multi-io DACs
before the speaker, thus it assigns DAC2/3 for multi-io and DAC4 for
the speaker for a standard laptop setup like a HP, a speaker, a mic-in
and a line-in. However, on Acer Aspire 6935, it seems that the
speaker pin 0x14 must be connected with either DAC1 or 2; otherwise it
results in silence by some reason, although the codec itself allows
the routing to DAC3/4.
As a workaround, the connection list of each pin is reduced to be
mapped to either only DAC1/2 or DAC3/4, so that the compatible
assignment as in kernel 3.1 is achieved.

VT1705 codec has two ADCs where the secondary ADC has no MUX but only
a fixed connection to the mic pin. This confused the driver and it
tries always overriding the input-source selection by assumption of
the existing MUX for the secondary ADC, resulted in resetting the
input-source at each time PM (including power-saving) occurs.
The fix is simply to check the existence of MUX for secondary ADCs in
the initialization code.

It's useful to print the error code when a called function fails so a
diagnosis of why it failed is possible. In this case, it fails because
we try to register some data for the wl12xx driver, but as the driver
is not configured, a stub function is used which simply returns -ENOSYS.
Let's do the simple thing for -rc and print the error code.
Also, the return code from platform_register_device() at each of these
sites was not being checked. Add some checking, and again print the
error code.
This should be fixed properly for the next merge window so we don't
issue error messages merely because a driver is not configured.
