sound/soc/soc-core.c: soc_remove_component() unconditionally calls
snd_soc_component_set_jack(component, NULL, NULL); on any components
being removed.

This means that on machines where the machine-driver does not provide
a jack through snd_soc_component_set_jack() es8316_disable_jack_detect()
will still get called and at this time es8316->jack will be NULL and
the es8316->jack->status check in es8316_disable_jack_detect() will
lead to a NULL pointer deref.

Fix this by checking for es8316->jack bein NULL at the start of
es8316_disable_jack_detect() and turn the function into a no-op in
that case.

Move the snd_soc_dai_set_tdm_slot() call from cht_codec_init() to
cht_codec_fixup(). There are 2 reasons for doing this:

1. This aligns the cht_bsw_nau8824 with all the other BYT/CHT machine
drivers which also do this from their codec_fixup function.

2. When using the SOF driver, things like the TDM info is set from the
topology file. Moving the call to the codec_fixup function, which gets
skipped when using the SOF driver avoids the call interfering with the
settings when using the SOF driver.

wm_adsp_read_data_word() used if (ret) to check for an error from
wm_adsp_read_raw_data_block(). While this is perfectly valid,
wm_adsp_read_raw_data_block() itself uses if (ret < 0) and three
calls to wm_adsp_read_data_word() also use if (ret < 0).

This creates an error check chain like this:

  1st) if (ret < 0) return ret;
  2nd) if (ret) return ret;
  3rd) if (ret < 0) ...

This can confuse the compiler into thinking that there are possible
returns > 0 from the middle if() that are not handled by the final
if(). If this was true it would lead to using uninitialized variables
later in the outer function.

Fix this by changing the test in wm_adsp_read_data_word() to be
if (ret < 0).

This fixes some minor cases where u32 or unsigned int types were used
to store big-endian data, and __be32 types used to store both big-endian
and cpu-endian data. This was producing sparse warnings.

Most cases resulted from using the same variable to hold the big-endian
value and its converted cpu-endian value. These can be simply fixed by
introducing another local variable, or avoiding storing the intermediate
value back into the original variable.

One special case is the raw_buf used in the compressed streams to transfer
data from DSP to user-side. The endian conversion happens in-place (as
there's no point introducing another buffer) so a cast to (__be32 *) is
added when passing it to wm_adsp_read_raw_data_block().

As the register map is 16-bit or 32-bit big-endian, the 24-bit
DSP words appear padded and with the bytes swapped. When reading a
raw stream of bytes, the pad bytes must be removed and the data bytes
swapped back to their original order.

The previous implementation of this assumed that the be32_to_cpu() in
wm_adsp_read_data_block() would swap back to little-endian. But this is
obviously only true on a little-endian CPU. It also made two walks
through the data, once to endian-swap and again to strip the pad bytes.

This patch re-works the code so that the endian-swap and unpad are done
together in a single walk, and it is not dependent on the endianness of
the CPU. The data_word_size argument to wm_adsp_remove_padding() has been
dropped because currently this is always 3.
