dmaengine: intel_mid_dma: move pm_runtime_put
Move pm_runtime_put() to the end of intel_mid_dma_free_chan_resources() because there is no sense in allowing runtime suspend while the driver is still accessing the device. Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Signed-off-by: Vinod Koul <vinod.koul@linux.intel.com>
