The "wlf,spkvdd-ena" GPIO needed by the bytcr_wm5102 driver
is made available through a gpio-lookup table.
This gpio-lookup table is registered by drivers/mfd/arizona-spi.c, which
may get probed after the bytcr_wm5102 driver.
If the gpio-lookup table has not registered yet then the gpiod_get()
will return -ENOENT. Treat -ENOENT as -EPROBE_DEFER to still keep
things working in this case.

Currently in slim_rx_mux_put, an RX channel gets added to a new list
even if it is already in one. This can mess up links and make either
it, the new list head, or both, get linked to the wrong entries.
This can cause an entry to link to itself which in turn ends up
making list_for_each_entry in other functions loop infinitely.
To avoid issues, always remove the RX channel from any list it's in
before adding it to a new list.

The .set_jack_detect() codec component callback is invoked during card
registration, which happens when the machine driver is probed.
The issue is that this callback can race with the bus suspend/resume,
and IO timeouts can happen. This can be reproduced very easily if the
machine driver is 'blacklisted' and manually probed after the bus
suspends. The bus and codec need to be re-initialized using pm_runtime
helpers.
Previous contributions tried to make sure accesses to the bus during
the .set_jack_detect() component callback only happen when the bus is
active. This was done by changing the regcache status on a component
remove. This is however a layering violation, the regcache status
should only be modified on device probe, suspend and resume. The
component probe/remove should not modify how the device regcache is
handled. This solution also didn't handle all the possible race
conditions, and the RT700 headset codec was not handled.
This patch tries to resume the codec device before handling the jack
initializations. In case the codec has not yet been initialized,
pm_runtime may not be enabled yet, so we don't squelch the -EACCES
error code and only stop the jack information. When the codec reports
as attached, the jack initialization will proceed as usual.

Commit 44f362c2cc6d ("ASoC: rockchip: i2s: switch BCLK to GPIO") added
pinctrl lookups, but did not skip the lookup if there was no pinctrl
device tied to the I2S controller. As a result, the lookup was done
on an invalid pointer in such cases, causing a kernel panic.
Only do the subsequent pinctrl state lookups and switch if a pinctrl
device was found.
i2s_pinctrl_select_bclk_{on,off} already guard against missing pinctrl
device or pinctrl state, so those two functions aren't touched.

Even in the presence of problems (here: rn_acp_deinit() might fail), it's
important to unregister all resources acquired during .probe() because
even if .remove() returns an error code, the device is removed.
As .remove() is only called after .probe() returned success, platdata
must be valid, so the first check in .remove() can just be dropped.
This is a preparation for making platform remove callbacks return void.

The function snd_soc_unregister_card() returned 0 unconditionally and most
callers don't care to check the return value. Make it return void and
adapt the callers that didn't ignore the return value before.

We discoverd that the state of BCLK on, LRCLK off and SD_MODE on
may cause the speaker melting issue. Removing LRCLK while BCLK
is present can cause unexpected output behavior including a large
DC output voltage as described in the Max98357a datasheet.
In order to:
1. prevent BCLK from turning on by other component.
2. keep BCLK and LRCLK being present at the same time
This patch switches BCLK to GPIO func before LRCLK output, and
configures BCLK func back during LRCLK is output.
Without this fix, BCLK is turned on 11 ms earlier than LRCK by the
da7219.
With this fix, BCLK is turned on only 0.4 ms earlier than LRCK by
the rockchip codec.

The initial settings will be written before the codec probe function.
But, the rt711->component doesn't be assigned yet.
If IO error happened during initial settings operations, it will cause the kernel panic.
This patch changed component->dev to slave->dev to fix this issue.
