SOF compilation broken for p4wq.c with recent Zephyr

[lyakh]

Describe the bug

Compiling p4wq.c breaks down for TGL:

/srv/home/jenkins/workspace/sof_config_build@2/zephyr/lib/os/p4wq.c:224: error: unknown field ‘srv’ specified in initializer

Regression

• This is a regression.

Steps to reproduce

• Update SOF to use a recent Zephyr version
• Build SOF for TGL

Relevant log output

/srv/home/jenkins/workspace/sof_config_build@2/zephyr/lib/os/p4wq.c:224: error: unknown field ‘srv’ specified in initializer
/srv/home/jenkins/workspace/sof_config_build@2/zephyr/lib/os/p4wq.c:224: warning: missing braces around initializer
/srv/home/jenkins/workspace/sof_config_build@2/zephyr/lib/os/p4wq.c:224: warning: (near initialization for ‘__init_static_init.<anonymous>’)

Impact

Major – Severely degrades functionality; workaround is difficult or unavailable.

Environment

Zephyr commit e22ca6b

Additional Context

No response

How come this is reported against Zephyr and not SoF?

@henrikbrixandersen I think it's the broken compiler, used by SOF to build for TGL #93027 . Supposedly building pure Zephyr with the same compiler would fail too. Let me try

UPDATE: managed to reproduce with west build -b intel_adsp/cavs25 -d build-p4wq zephyr/tests/kernel/sched/deadline using the same toolchain:

zephyr/lib/os/p4wq.c:224: error: unknown field ‘srv’ specified in initializer
zephyr/lib/os/p4wq.c:224: warning: missing braces around initializer
zephyr/lib/os/p4wq.c:224: warning: (near initialization for ‘__init_static_init.<anonymous>’)

...but the reason I've filed it here is because it worked before and it's 175da6b that initroduced this breakage
