From 2578180858e80261f8ba133dc998d5fb5b54d547 Mon Sep 17 00:00:00 2001 From: Peter Huewe Date: Wed, 13 Feb 2013 03:58:15 +0100 Subject: [PATCH] staging/rtl8187se: Remove code without effect The local variable u4bAcParam is never read/used after assignment, thus we can remove the declaration, assignment and any related code. -> the local variables u1bAIFS, eACI and pAcParam can also be removed.
