Julia Lawall 33d7f77850 ASoC: Clean up error handling in MPC5200 DMA setup
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:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
