Subject: 8139cp: fix coherent mapping leak in error path.
X-Git-Tag: v3.7-rc8~6^2
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=892a925e42adb8192a3c832ad29cbc780fc466f6;p=pandora-kernel.git

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
