Tyrel Datwyler 756af9c642 ibmveth: fix DMA unmap error in ibmveth_xmit_start error path ... Commit 33a48ab105 ("ibmveth: Fix DMA unmap error") fixed an issue in the normal code path of ibmveth_xmit_start() that was originally introduced by Commit 6e8ab30ec6 ("ibmveth: Add scatter-gather support"). This original fix missed the error path where dma_unmap_page is wrongly called on the header portion in descs[0] which was mapped with dma_map_single. As a result a failure to DMA map any of the frags results in a dmesg warning when CONFIG_DMA_API_DEBUG is enabled. ------------[ cut here ]------------ DMA-API: ibmveth 30000002: device driver frees DMA memory with wrong function [device address=0x000000000a430000] [size=172 bytes] [mapped as page] [unmapped as single] WARNING: CPU: 1 PID: 8426 at kernel/dma/debug.c:1085 check_unmap+0x4fc/0xe10 ... <snip> ... DMA-API: Mapped at: ibmveth_start_xmit+0x30c/0xb60 dev_hard_start_xmit+0x100/0x450 sch_direct_xmit+0x224/0x490 __qdisc_run+0x20c/0x980 __dev_queue_xmit+0x1bc/0xf20 This fixes the API misuse by unampping descs[0] with dma_unmap_single.
