[1/1] dmaengine: fsl-edma: fix DMA channel leak in eDMAv4 commit: 4ee632c82d2dbb9e2dcc816890ef182a151cbd99 Best regards,

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().
