dma-trace.c: fix unsupported mtrace_printf("%s", ...) string specifier

marc-hb · lgirdwood · commit dbc8e0fb31e5 · 2022-02-21T10:22:44.000Z
The dictionary does not support character strings. Fixes commit c11562b ("dma-trace: Align DMA buffer correctly to fix dma tracing issues") Take the opportunity to log the d pointer (which _is_ supported). Fixes the following error message: TIMESTAMP (us) DELTA C# COMPONENT LOCATION CONTENT error: String printing is not supported [ 2.604167] ( 0.000000) c0 dma-trace src/trace/dma-trace.c:266 ERROR <String @ 0xbe035e60> failed: no DMAC Signed-off-by: Marc Herbert <marc.herbert@intel.com>
