4.15-stable review patch. If anyone has any objections, please let me know.
------------------ From: Dan Carpenter <[email protected]> [ Upstream commit 7814f552ff826fefa5e1b24083c7a06a9378e9ef ] The dma_map_sg() function returns zero on error and positive values on success. We want to return -ENOMEM on failure here and zero on success.
