  "message": "dma-mapping: fix sync_single_range_* DMA debugging\n\nCommit 5fd75a7850b5 (dma-mapping: remove unnecessary sync_single_range_*\nin dma_map_ops) unified not only the dma_map_ops but also the\ncorresponding debug_dma_sync_* calls.  This led to spurious WARN()ings\nlike the following because the DMA debug code was no longer able to detect\nthe DMA buffer base address without the separate offset parameter:\n\nWARNING: at lib/dma-debug.c:911 check_sync+0xce/0x446()\nfirewire_ohci 0000:04:00.0: DMA-API: device driver tries to sync DMA memory it has not allocated [device address\u003d0x00000000cedaa400] [size\u003d1024 bytes]\nCall Trace: ...\n [\u003cffffffff811326a5\u003e] check_sync+0xce/0x446\n [\u003cffffffff81132ad9\u003e] debug_dma_sync_single_for_device+0x39/0x3b\n [\u003cffffffffa01d6e6a\u003e] ohci_queue_iso+0x4f3/0x77d [firewire_ohci]\n ...\n\nTo fix this, unshare the sync_single_* and sync_single_range_*\nimplementations so that we are able to call the correct debug_dma_sync_*\nfunctions.\n\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: Clemens Ladisch \u003cclemens@ladisch.de\u003e\nCc: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: Konrad Rzeszutek Wilk \u003ckonrad.wilk@oracle.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
