From b926050cb1bfa64e575fab5e4eb3d2a15d349464 Mon Sep 17 00:00:00 2001 From: Peter Huewe Date: Wed, 13 Feb 2013 03:58:16 +0100 Subject: [PATCH] staging/rtl8187se: Remove code without effect The local variable AcParam is only assigned to but not read/used afterwards, thus it and all related code can be removed. The bFollowLegacySetting variable and check can also be removed as it is always true.
