Kuninori Morimoto 2ce1b21cb3 ASoC: rsnd: fixup DMAEngine API ... commit d5bb69dc54 ("ASoC: sh: rcar: dma: : use proper DMAENGINE API for termination") updated DMAEngine API _all() to _sync(), but it should be _async(). _all() and _async() are almost same, the difference is only return error code. _sync() will call dmaengine_synchronize() and will be kernel panic. This patch is needed for v5.15 or later.
