The ASoC machine drivers for this board were only provided as examples
for the new AT91 ASoC platform driver. Since the ETI-B1 board is
proprietary and there are other AT91 ASoC machine drivers available,
it makes sense to remove these drivers.

Add a new API call snd_soc_dapm_nc_pin() which allows machine drivers to
mark pins as being permanently disabled. At present this is identical
to snd_soc_dapm_disable_pin() except in terms of improving the internal
documentation of machine drivers that use it. The intention is that in
future it will be extended to provide additional features such as hiding
controls that are only relevant to paths using the disconnected pin.

Function dapm_mux_update_power needs enum index mux and register mask value val
as parameters, but it only has a parameter val, and uses it as both val and mux.
snd_soc_test_bits(widget->codec, e->reg, mask, val) val is register mask here,
e->texts[val] but val should be enum index mux here.
This patch adds a new param mux to fix it.

The test (ssc != NULL) can only be reached if the call to the function
ssc_request, the result of which ssc is assigned, succeeds. Moreover,
two statements assign NULL to ssc just before a return, which is useless
since it is a local variable. So, we suggest to delete the test and
the two assignments.
A simplified version of the semantic match that finds this problem is
as follows:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@bad_null_test@
expression x,E;
@@
x = ssc_request(...)
... when != x = E

The error handling in neo1973_init is incorrect:
* If platform_device_add fails, we go on with the rest of the
initialization instead of bailing out. Things will break when the
module is removed (platform_device_unregister called on a device
that wasn't registered.)
* If i2c_add_driver fails, we return an error so the module will not
load, but we don't unregister neo1973_snd_device, so we are leaking
resources.
