ASoC: dapm: Check for NULL widget in dapm_update_dai_unlocked
DAIs linked to the dummy will not have an associated playback/capture
widget, so we need to skip the update in that case.

ASoC: topology: unload physical dai link in remove
soc_tplg_link_config() will find the physical dai link and call
soc_tplg_dai_link_load() to load the BE dai link. Currently remove_link()
is only used to remove the FE dai link which is created by the topology.
The BE dai link cannot however be unloaded in snd_soc_tplg_component
_remove(), which is problematic if anything needs to be released or
reinitialized.

This patch aligns the definitions of dynamic types with the existing
UAPI and adds a new remove_backend_link() routine to unload the the BE
dai link when snd_soc_tplg_component_remove() is invoked.

ASoC: soc-core: clear platform pointers on error
Originally snd_soc_init_platform was not cleaning up its pointers, this
was fixed to always reallocate dynamic memory but created a memory leak
when snd_soc_init_platform was called multiple times during the same
probe attempt and also threw away any changes made to the struct between
calls. In order to avoid reallocating memory that is still valid, the
behaviour will be changed to clear the dynamically set pointers on a
probe error and a unregister event and snd_soc_init_platform will go
back to its original behaviour of only allocating null pointers so it will
stop throwing away valid changes.

ASoC: dapm: Add warnings for widget overwrite when adding route
Currently, in some complex cases, more than one widgets have same
name and registed from differnt dapm context, and route add from
another context too. When snd_soc_dapm_add_route, the previous
registered widget will overwritten by the latest same name widget,
will cause unexpect error. For Asoc framework we cant avoid this
situation and we cant decide which widget that wanted with route.
At least we can give users a notice.

ASoC: dapm: Only power up active channels from a DAI
Currently all widgets attached to a DAI link will be powered
up when the DAI is active, however this may include routes
that are not actually in use if there are unused channels
available on the DAI.

The macros for creating AIF widgets already include an entry for
slot, it is proposed to change that to channel. The effective
difference here being respresenting the logical channel index
rather than the physical slot index. The CODECs currently
using the slot entry on the DAPM_AIF macros are using it in
a manner consistent with this, the CODECs not using it just
have the field set to zero.

A variable is added to snd_soc_dapm_widget to represent
this channel index and then for each AIF widget attached to
a DAI this is compared against the number of channels on
the stream. Enabling the links for those which will be in
use. This has the nice property that the CODECs which haven't
used the slot/channel entry in the macro will function exactly
as before due to all the AIF widgets having a channel of zero
and a stream by definition having at least one channel.

ASoC: dapm: fix use-after-free issue with dailink sname
Commit 7620fe9161 ("ASoC: topology: fix memory leak in
soc_tplg_dapm_widget_create") fixed a memory leak issue, but
additional tests and KASAN reports show a use-after-free in soc-dapm.

The widgets are created with a kmemdup operating on a template. The
"name" string is also duplicated, but the "sname" string is not. As a
result, when the template is freed after widget creation, its sname
string is still used.

Fix by explicitly duplicating the "sname" string, and freeing it when
required.

ASoC: rsnd: fixup TDM Split mode check for CTU
Renesas sound card need to judge that whether it is using
"TDM Split mode". To judge it and for other purpose, it has
rsnd_parse_connect_simple() and rsnd_parse_connect_graph(),
but these are using different judgement policy for
TDM Split mode.
It is pointless and confusable.
This patch add new rsnd_parse_tdm_split_mode() and use common
judgement policy for simple-card/audio-graph.

Without this patch, CTU will be judged as TDM Split mode
on audio-graph card.

2. Add the remove_route() routine that will be called while

ASoC: pcm512x: Fix clocking calculations when not using the PLL
The rationale behind the current calculation is somewhat obscure [1]
and can yield slightly wrong dividers in certain cases, which the
machine drivers for some boards (like the HiFiBerry DAC+ Pro)
seemingly try to circumvent, by updating the rate fraction so as to
suit this calculation.

The updated calculation should correctly yield the smallest bit clock
rate that would fit the frame.

ASoC: pcm512x: Implement the set_bclk_ratio interface
Some boards, such as the HiFiBerry DAC+ Pro, use a pair of external
oscillators, to generate 44.1 or 48kHz multiples and are forced to
resort to hacks [1] in order to support 24-bit data without ending up
with fractional dividers.  This patch allows the machine driver to use
32-bit frames for 24-bit data to avoid such issues.

Although the datasheet (p. 15) seems to suggest that only a handful
of ratios are supported, it's not very explicit about it, so we allow
the full range of values supported by the underlying register in the
callback, to avoid needlessly rejecting potentially usable
configurations.

ASoC: soc-core: use for_each_link_codecs() for dai_link codecs V2
We can use for_each_link_codecs() without waiting
for_each_rtd_codec_dai() on soc_bind_dai_link().
Let's use for_each macro.
