Subject: [PATCH] ASoC: SOF: dma-trace: Pass pointer to params_ext struct in trace_init()
Git-commit: bab05b508ebfde32a14880696a13820d54510fcb
Patch-mainline: v5.18-rc1
References: jsc#PED-850
Instead of passing a pointer to the stream_tag within the
struct sof_ipc_dma_trace_params_ext, pass the pointer to the containing
struct.
AMD needs to update buffer.phy_addr (and don't really use the stream_tag)
for the trace implementation.
