[PATCH 3/3] dmaengine: imx-sdma: remove unused function

From: Baoyou Xie
Date: Sat Sep 24 2016 - 01:01:29 EST


We get 1 warning when building kernel with W=1:
drivers/dma/imx-sdma.c:673:13: warning: 'sdma_handle_channel_loop' defined but not used [-Wunused-function]

In fact, this function is called by no one and not exported,
so this patch removes it.
