8139cp: fix coherent mapping leak in error path.
cp_open
[...]
rc = cp_alloc_rings(cp);
if (rc)
return rc;
cp_alloc_rings
[...]
mem = dma_alloc_coherent(&cp->pdev->dev, CP_RING_BYTES,
&cp->ring_dma, GFP_KERNEL);
- cp_alloc_rings never frees the coherent mapping it allocates
- neither do cp_open when cp_alloc_rings fails
