Subject: [PATCH v1] DMA:omap-dma:Avoid build error by changing the function name

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

Change the name of the function omap_dma_filter_fn to avoid
the following build error in linux kernel version 4.4 :

drivers/dma/dma-omap.c:1273:6: error:
redefinition of 'omap_dma_filter_fn'

Signed-off-by: Venkat Prashanth B U <venkat.prashanth2498@...il.com>
Changes for v1:
- Edited subject and description of the patch to fit with the change
  done in the code base, as suggested by Vinod Koul.

- In order to avoid  issues like backporting on stable the
  checkpatch.pl issues are dropped as suggested by Vinod Koul.
