From: Venkat Prashanth B U <venkat.prashanth2498@gmail.com>

This is the patch to the omap-dma.c file that fixes
the following issues:

1.redefinition of 'omap_dma_filter_fn' in the line 1273
of drivers/dma/omap-dma.c

2.drivers/dma/omap-dma.c:341: ERROR: code indent should
use tabs where possible reported by ./checkpatch.pl

3.drivers/dma/omap-dma.c:749: WARNING: Missing a blank
line after declarations reported by ./checkpatch.pl
