From bc822e80170d672dd8ff0d07c521cf72f491cb6c Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 6 Nov 2018 13:45:10 +0000 Subject: dmaengine: sa11x0: unexport sa11x0_dma_filter_fn and clean up As we now have no users of sa11x0_dma_filter_fn() in the tree, we can unexport this function, and remove the now unused header file.
