ASoC: wm_adsp: Fix dma-unsafe read of scratch registers [ Upstream commit 20e00db2f59bdddf8a8e241473ef8be94631d3ae ] Stack memory isn't DMA-safe so it isn't safe to use either regmap_raw_read or regmap_bulk_read to read into stack memory. The two functions to read the scratch registers were using stack memory and regmap_raw_read. It's not worth allocating memory just for this trivial read, and it isn't time-critical. A simple regmap_read for each register is sufficient.
