ASoC: Updates for v6.4

The bulk of the commits here are for the conversion of drivers to use
void remove callbacks but there's a reasonable amount of other stuff
going on, the pace of development with the SOF code continues to be high
and there's a bunch of new drivers too:

 - More core cleanups from Morimto-san.
 - Update drivers to have remove() callbacks returning void, mostly
   mechanical with some substantial changes.
 - Continued feature and simplification work on SOF, including addition
   of a no-DSP mode for bringup, HDA MLink and extensions to the IPC4
   protocol.
 - Hibernation support for CS35L45.
 - More DT binding conversions.
 - Support for Cirrus Logic CS35L56, Freescale QMC, Maxim MAX98363,
   nVidia systems with MAX9809x and RT5631, Realtek RT712, Renesas R-Car
   Gen4, Rockchip RK3588 and TI TAS5733.

ALSA: Use of_property_read_bool() for boolean properties

2023-04-19T06:26:08+00:00

It is preferred to use typed property access functions (i.e.
of_property_read_ functions) rather than low-level
of_get_property/of_find_property functions for reading properties.
Convert reading boolean properties to to of_property_read_bool().

ALSA: ppc/tumbler: Use of_property_present() for testing DT property presence

2023-04-19T06:25:57+00:00

It is preferred to use typed property access functions (i.e.
of_property_read_ functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.

ALSA: ppc/powermac: Convert to platform remove callback returning void

2023-03-20T13:07:06+00:00

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

ALSA: ppc: fix unused function local variable

2023-02-09T07:04:36+00:00

The function local variable is not used anymore, while it is left.

This commit deletes it.

ALSA: core: Make snd_card_free() return void

The function returns 0 unconditionally. Make it return void instead and
simplify all callers accordingly.

ALSA: ppc: keywest: Convert to i2c's .probe_new()

2022-11-19T08:43:50+00:00

The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.

Pull sound updates from Takashi Iwai:
 "The majority of changes are ASoC drivers (SOF, Intel, AMD, Mediatek,
  Qualcomm, TI, Apple Silicon, etc), while we see a few small fixes in
  ALSA / ASoC core side, too.

  Here are highlights:

  Core:
   - A new string helper parse_int_array_user() and cleanups with it
   - Continued cleanup of memory allocation helpers
   - PCM core optimization and hardening
   - Continued ASoC core code cleanups

  ASoC:
   - Improvements to the SOF IPC4 code, especially around trace
   - Support for AMD Rembrant DSPs, AMD Pink Sardine ACP 6.2, Apple

i2c: Make remove callback return void

2022-08-16T10:46:26+00:00

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.
