From 4665be0e952f68306cc6fba2cce68b940a7ec78c Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Fri, 8 Mar 2024 13:47:50 +0000 Subject: dmaengine: pch_dma: remove unused function chan2parent The helper function chan2parent is not used and has never been used since the first commit to the code back in 2010. The function is redundant and can be removed.
