From 01343537e6da3398ecea205ff1d579e4dc226b93 Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Thu, 9 Feb 2012 21:08:57 +0100 Subject: [PATCH] brcm80211: smac: remove redundant assignments from txpwrctrl_pwr_setup_nphy The function wlc_phy_txpwrctrl_pwr_setup_nphy() does assign a local variable target_pwr_qtrdbm in several code paths, but in the end all code paths are coming to an assignment of that variable which does override all previous. So those early and redundant assignments have been removed.
