If anyone has any objections, please let me know. ------------------ From: Frank Li 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().
