changed the installation instructions to point at this repo so people dont accidentally just copy paste the install instructions and get the out of date ones from seeed instead.
The lib modules folder looks like `/lib/modules/6.1.21-v8+/build`, which
means that the previous regex doesn't capture anything after the `-` and
therefore it fails to detect the kernel version.
The regex now aligns with the other detection method and this works fine
on my machine™
Kernel 6.1 onwards seems to have strings re-arranged so that a newline
no long happens right before the "Linux version" string.

i2c: Make remove callback return void
The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

ASoC: simple-card-utils: Move snd_soc_component_is_codec to be local
The helper function snd_soc_component_is_codec is based off the
presence of the non_legacy_dai_naming flag. This isn't super robust
as CPU side components may also specify this flag, and indeed the
kernel already contains a couple that do. After componentisation there
isn't really a totally robust solution to identifying what is a CODEC
driver, without introducing a flag specifically for that purpose, and
really the desirable direction to move in is that the distinction
doesn't matter.
This patch does two things to try to mitigate these problems. Firstly,
now that all the other users of the helper function have been removed,
it makes the helper function local to the driver rather, than being
part of the core. This should help to discourage any new code from
being created that depends on the CODEC driver distinction. Secondly,
it updates the helper function itself to use the endianness flag
rather than the non_legacy_dai_naming flag. The endianness flag is
definitely invalid on a CPU side component, so it a more reliable
indicator that the device is definitely a CODEC. The vast majority of
buses require the CODEC to set the endianness flag, so the number of
corner cases should be fairly minimal. It is worth noting that CODECs
sending audio over SPI, or built into the CPU CODECs are potential
corner cases, however the hope is that in most cases those types of
devices do not consitute a simple audio card.

ASoC: simple-card-utils: Make asoc_simple_clean_reference() return void
asoc_simple_clean_reference() returns zero unconditionally. Letting it
return void instead makes it easier to see in the caller that there is no

This is a preparation for making platform remove callbacks return void.

ASoC: soc-pcm: Use different sequence for start/stop trigger
On stream stop currently we stop the DMA first followed by the CPU DAI.
This can cause underflow (playback) or overflow (capture) on the DAI side
as the DMA is no longer feeding data while the DAI is still active.
It can be observed easily if the DAI side does not have FIFO (or it is
disabled) to survive the time while the DMA is stopped, but still can
happen on relatively slow CPUs when relatively high sampling rate is used:
the FIFO is drained between the time the DMA is stopped and the DAI is
stopped.
It can only fixed by using different sequence within trigger for 'stop' and
'start':
case SNDRV_PCM_TRIGGER_START:
case SNDRV_PCM_TRIGGER_RESUME:
case SNDRV_PCM_TRIGGER_PAUSE_RELEASE:
Trigger order: dai_link, DMA, CPU DAI then the codec
case SNDRV_PCM_TRIGGER_STOP:
case SNDRV_PCM_TRIGGER_SUSPEND:
case SNDRV_PCM_TRIGGER_PAUSE_PUSH:
Trigger order: codec, CPU DAI, DMA then dai_link

ASoC: simple-card: Add support for codec2codec DAI links
Following the example in cb2cf0de1174 ("ASoC: soc-core: care Codec <->
Codec case by non_legacy_dai_naming"), determine if a DAI link contains
only codec DAIs by examining the non_legacy_dai_naming flag in each
DAI's component.
For now, we assume there is only one or a small set of valid PCM stream
parameters, so num_params == 1 is good enough. We also assume that the
same params are valid for all supported streams. params is set to the
subset of parameters common among all DAIs, and then the existing code
automatically chooses the highest quality of the remaining values when
the link is brought up.
