From f9b6721a9cef94908467abf7a2cacbd15a7d23cb Mon Sep 17 00:00:00 2001 From: Joern Engel Date: Tue, 16 Sep 2014 16:23:18 -0400 Subject: [PATCH] qla_target: improve qlt_unmap_sg() Remove the inline attribute. Modern compilers ignore it and the function has grown beyond where inline made sense anyway. Remove the BUG_ON(!cmd->sg_mapped), and instead return if sg_mapped is not set. Every caller is doing this check, so we might as well have it in one place instead of four.
