dmaengine: cppi41: Fix list not empty warning on module removal
If musb controller is configured with USB peripherals and we have enumerated with a USB host, we can get warnings on removal of the modules: WARNING: CPU: 0 PID: 1269 at drivers/dma/cppi41.c:391 cppi41_dma_free_chan_resources Fix the issue by adding the missing pm_runtime_get to cppi41_dma_free_chan_resources to make sure the pending work list is cleared on removal. Fixes: fdea2d09b997 ("dmaengine: cppi41: Add basic PM runtime support") Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
