Subject: [PATCH] ASoC: SOF: Introduce opaque storage of private data for firmware tracing
Git-commit: 08341b27bd2ee3c79265ef7925b3bc68a1790ab9
Patch-mainline: v5.19-rc1
References: jsc#PED-850

Firmware tracing implementations can allocate and store their privately
used data behind the fw_trace_pdata pointer instead of adding more
members to struct snd_sof_dev.
