From: Fabio Estevam <[email protected]>

Commit 2436bdcda53f ("dma-coherent: remove the DMA_MEMORY_MAP and DMA_MEMORY_IO flags") missed to remove the 'dma' variable causing the following build warning:

arch/arm/mach-imx/mach-mx31moboard.c:478:6: warning: unused variable 'dma' [-Wunused-variable]

Remove the unused 'dma' variable.
