OMAP: DSS2: DSI: fix IRQ debug prints
print_irq_status functions can be called with empty irq status when full irq debugging is enabled. This patch makes print_irq_status functions return immediately when given an empty irq status to lessen the debug spam slightly. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
