Cezary Rojewski b6c14d7a83 dmaengine dw: Revert "dmaengine: dw: Enable runtime PM" ... This reverts commit 842067940a. For some solutions e.g. sound/soc/intel/catpt, DW DMA is part of a compound device (in that very example, domains: ADSP, SSP0, SSP1, DMA0 and DMA1 are part of a single entity) rather than being a standalone one. Driver for said device may enlist DMA to transfer data during suspend or resume sequences. Manipulating RPM explicitly in dw's DMA request and release channel functions causes suspend() to also invoke resume() for the exact same device. Similar situation occurs for resume() sequence. Effectively renders device dysfunctional after first suspend() attempt. Revert the change to address the problem.
