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 <[email protected]>
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.

Okay I do not see this error, which tree are you running?
In code is see omap_dma_filter_fn is used everywhere and no reference to
omap_dma_filter_func
Adding peter too..

What is your config regarding to omap_dma?
in the include/linux/omap-dmaengine.h :
#if defined(CONFIG_DMA_OMAP) || (defined(CONFIG_DMA_OMAP_MODULE) &&
defined(MODULE))
bool omap_dma_filter_fn(struct dma_chan *, void *);
#else
static inline bool omap_dma_filter_fn(struct dma_chan *c, void *d)
{
return false;
}
#endif
DMA_OMAP enables the build of drivers/dma/omap-dma.c

I have not seen this either, and looking at the code I don't think it is
possible. Not with what we have upstream.

this certainly breaks the omap_dma driver on non DT booted systems.
