From 4a0732d1f93ff52b0e74a61302260b9417f6db61 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 7 Feb 2014 14:50:38 +0300 Subject: [PATCH] ath5k: shifting the wrong variable for AR5K_AR5210 In the original code we shift "AR5K_PHY(256) >> 28" which is zero but the intent was to shift the return value of ath5k_hw_reg_read() like we do a couple lines later.
