8139cp: Add dma_mapping_error checking Self explanitory dma_mapping_error addition to the 8139 driver, based on this: https://bugzilla.redhat.com/show_bug.cgi?id=947250 It showed several backtraces arising for dma_map_* usage without checking the return code on the mapping. Add the check and abort the rx/tx operation if its failed. Untested as I have no hardware and the reporter has wandered off, but seems pretty straightforward.
