imx8_get_reply(), imx8m_get_reply(), atom_get_reply(), bdw_get_reply().
hda_dsp_ipc_get_reply() have additional check in place for PROBES and
special handling of PM messages.
Add a generic implementation to the core which can be used as drop in

The reply size check is changed to be able to handle cases when the reply
size is not know beforehand (this is the case for PROBES and
DEBUG_MEM_USAGE for example).

When reporting a jack unplug there's no need to make the reported
flags conditional on which flags were reported during the plug
event. It's perfectly safe to report all flags and buttons as
not-present and let the higher code filter for changes.
There's also no need to make two separate snd_soc_jack_report()
calls for presence flags and button flags. It can all be done in
one report.

We assume the adr order described in a snd_soc_acpi_link_adr array is
jack -> amp -> mic. We follow the same order to implement the topology.
We will need a special topology if we configure a snd_soc_acpi_link_adr
array with different order. Adding a check and a warning message can
remind people to keep the order when adding a new snd_soc_acpi_link_adr
array.

Currently, we assign SoundWire DAI link id according to the order in
the link address table, with the assumption that the headset codec is
listed first, then amplifiers and last capture devices. If the headset
codec is not present in a platform, the dai link for amplifiers will be
shifted, which can be handled in two ways
a) modify the topology to renumber the dailink changes
b) keep the dailink numbers constant in topology but also avoid the
variations in the machine driver.
This patch adds support for option b), the dailink index for amplifiers
and capture devices becomes fixed.

Special thanks to Nathan Chancellor who fixed the Clang bug[1][2]. This
bugfix only appears in Clang 14.0.0, so older versions still contain
the bug and -Wimplicit-fallthrough won't be enabled for them, for now.
This concludes a long journey and now we are finally getting rid
of the unintentional fallthrough bug-class in the kernel, entirely. :)
