From ed50e07d6a8eae1c079b637926811d7500e8dd9e Mon Sep 17 00:00:00 2001 From: Frank Li Date: Mon, 27 Nov 2023 16:43:25 -0500 Subject: [PATCH] dmaengine: fsl-edma: fix DMA channel leak in eDMAv4 commit 4ee632c82d2dbb9e2dcc816890ef182a151cbd99 upstream. Allocate channel count consistently increases due to a missing source ID (srcid) cleanup in the fsl_edma_free_chan_resources() function at imx93 eDMAv4. Reset 'srcid' at fsl_edma_free_chan_resources().
