[PATCH 2/2] ASoC: SOF: dma-trace: Pass pointer to params_ext struct in trace_init()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

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.
