      ASoC: SOF: amd: Fix for handling spurious interrupts from DSP · 2e7c6652
      V sujith kumar Reddy authored
      As interrupts are Level-triggered,unless and until we deassert the register
      the interrupts are generated which causes spurious interrupts unhandled.
      
      Now we deasserted the interrupt at top half which solved the below
      "nobody cared" warning.
      
      warning reported in dmesg:
      	irq 80: nobody cared (try booting with the "irqpoll" option)
      	CPU: 5 PID: 2735 Comm: irq/80-AudioDSP
