ARM: edma: Clean up and simplify the code around irq request
Get the two interrupt line number at the same time by merging the two instance of if(node){}else{} places. replace the &pdev->dev with the already existing dev which makes it possible to collapse lines with devm_request_irq() Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>
