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.

Currently the compressed streams in DSP firmwares are
identified essentially by looking at a fixed location inside
the firmware. This is fragile and also limits things to a
single compressed stream.
Here a new form of firmware parameter is added, the HOST_BUFFER
which identifies a compressed stream from meta-data in the
firmware file. This is more robust and allows for the possiblity
of using multiple streams per core in the future. Currently the
implementation is still limited to a single stream and will
use the first HOST_BUFFER parameter encountered. If there aren't
any HOST_BUFFER parameters it will fall back to the legacy way
of finding the host buffer.

Currently when creating ALSA control names for the DSP the length of any
prefix applied to the CODEC is not taken into account. Whilst this is
mostly harmless it does result in ALSA doing the truncation of the
control names and printing a warning. It is better to have the driver do
the truncation so it can truncate from the start of parameter name
itself to give a greater chance of the result maintain a unique name.

Commit 6396bb2215 ("treewide: kzalloc() -> kcalloc()") was
overlooked when doing some refactoring to the algorithm list
handling, which lead to twice as much buffer being allocated
as required for reading the algorithm list. A kcalloc is no
longer appropriate since the allocation size is now in bytes
not registers, as such change back to kzalloc.

The current code that reads the algorithm list from the DSP is
somewhat unclear, it converts directly from bytes to registers using
a hard coded divide by 2. Most offsets are usually handled in DSP
words within the driver and there is a function specifically for
converting from words to register addresses. So update the handling
to use these. This also removes the assumption that the registers
are 16-bit word addressed, which will no longer be true on some of
our newer parts.

This is a very big update, mainly due to a huge set of new drivers some
of which are individually very large. We also have a lot of fixes for
the topology stuff, several of the users have stepped up and fixed some
the serious issues there, and continued progress on the transition away
from CODEC specific drivers to generic component drivers.
- Many fixes for the topology code, including fixes for the half done
v4 ABI compatibility from Guenter Roeck and other ABI fixes from
Kirill Marinushkin.
- Lots of cleanup for Intel platforms based on Realtek CODECs from Hans
de Goode.
- More followups on removing legacy CODEC things and transitioning to

- Conversion of OMAP DMA to the new, more standard SDMA-PCM driver.
- A series of fixes and updates to the rather elderly Cirrus Logic SoC
drivers from Alexander Sverdlin.
- Qualcomm DSP support from Srinivas Kandagatla.
- New drivers for Analog SSM2305, Atmel I2S controllers, Mediatek

Normal 512-byte get/set of a TLV isn't supported but we were
registering the normal get/set anyway and relying on omitting
the SNDRV_CTL_ELEM_ACCESS_[READ|WRITE] flags to prevent them
being called.
Trouble is if this gets broken in the core ALSA code - as it has
been since at least 4.14 - the standard get/set can be called
unexpectedly and corrupt memory.
There's no point providing functions that won't be called and
it's a trivial change. The benefit is that if the ALSA core gets
broken again we get a big fat immediate NULL dereference instead
of a memory corruption timebomb.

For controls marked write-only don't initialize the cache from the
content of the DSP memory. We stil need the cache for any new data
that is written to this control, and we need to return something
for a read of the ALSA control because most user-side code assumes
all ALSA controls are readable. The cache is already created zero-
filled so the only change needed is to skip populating it from
DSP memory if the control isn't readable.

The checks for whether another region/block header could be present
are subtracting the size from the current offset. Obviously we should
instead subtract the offset from the size.
The checks for whether the region/block data fit in the file are
adding the data size to the current offset and header size, without
checking for integer overflow. Rearrange these so that overflow is
impossible.

As requirements to bring up audio paths are continuous getting tighter
and the DSP download to most ADSP devices happens over an external bus
it can become an important factor in the path bring up time. As such
sometimes it is a reasonable trade off to download the firmware ahead of
when it will be required and take a small hit on power consumption for
keeping the core powered up.
This "preloading" adds an additional control for each DSP core "DSPx
Preload Switch" that when set to true will power up the DSP core and
download the firmware currently selected in the "DSPx Firmware" control.
Whilst the core is preloaded the current firmware can not be changed and
the CODEC will be kept powered up and SYSCLK held on. Although future
improvements may allow the SYSCLK to be powered down as well because
the hardware only requires SYSCLK whilst the download is actually taking
place, but this is not covered in this series.
