From: Magnus Lindholm <linmag7@xxxxxxxxx> [ Upstream commit 5233e3235dec3065ccc632729675575dbe3c6b8a ] A null dereference or oops exception will eventually occur when qla1280.c driver is compiled with DEBUG_QLA1280 enabled and ql_debug_level > 2. I think its clear from the code that the intention here is sg_dma_len(s) not length of sg_next(s) when printing the debug info.
