[PATCH 1/1] dmaengine: fsl-edma: fix DMA channel leak in eDMAv4

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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().
