X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=731e6f007aa2d07fc1a420bffeb7c9e8226e89e6;p=openwrt%2Fstaging%2Fblogic.git net: ti: cpmac: Use the correct function to free some resources. In 'cpmac_open', 'dma_alloc_coherent' has been used to allocate some resources, so we need to free them using 'dma_free_coherent' instead of 'kfree'. Also, we don't need to free these resources if the allocation has failed. So I have slighly modified the goto label in this case. Signed-off-by: Christophe JAILLET Signed-off-by: David S.
