From cb7911694771faf16930b72a104d3cd41d500e2c Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Fri, 6 May 2016 00:16:17 +0100 Subject: [PATCH] target: need_to_release is always false, remove redundant check and kfree The removal the #ifdef'd code on CONFIG_ARCH_HAS_SG_CHAIN in commit 02c4de53add1b79 ("target/rd: always chain S/G list") removed the setting of need_to_release to true, so we are now left with need_to_release always being false and hence the conditional kfree is never reached. Clean up the dead code by removing need_to_release and the conditional kfree.
