Alexander.Barabash@dell.com 10d55ea613 ioat: ioat_alloc_ring() failure handling. ... [ Upstream commit b0b5ce1010 ] If dma_alloc_coherent() returns NULL in ioat_alloc_ring(), ring allocation must not proceed. Until now, if the first call to dma_alloc_coherent() in ioat_alloc_ring() returned NULL, the processing could proceed, failing with NULL-pointer dereferencing further down the line.
