The sdma_handle_channel_loop() function was modified in one patch
and removed in another, and the merge between those patches left
an unused function in place:

drivers/dma/imx-sdma.c:673:13: error: 'sdma_handle_channel_loop' defined but not used [-Werror=unused-function]

This removes it again.

Hi Vinod,

I still see the warning in linux-next, can you apply the patch?

The problem was fixed after you applied the patch, but it seems the
same one is now back in linux-next.

Opps I am sorry for that.

To prepare for pull request I rebased my next, and I fixed it while merging
with tty. I was planning to send this to Linus as reference.

But then i had to redo this as I merged some other code not going
for 4.9 and messed up in second try.

Thanks for pointing it out. It is fixed now and pushed
