      ASoC: Clean up error handling in MPC5200 DMA setup · 33d7f778

      Error handling code following a kzalloc should free the allocated data.
      Error handling code following an ioremap should iounmap the allocated data.
      
      The semantic match that finds the first problem is as follows:
