dmaengine: omap-dma: explicitly freeup irq
dmaengine device should explicitly call devm_free_irq() when using devm_request_irq(). The irq is still ON when devices remove is executed and irq should be quiesced before remove is completed. Signed-off-by: Vinod Koul <vinod.koul@intel.com> Acked-by: Peter Ujfalusi <peter.ujfalusi@ti.com>
