Subject: [patch] ath5k: shifting the wrong variable for AR5K_AR5210
Date: Fri, 7 Feb 2014 14:50:38 +0300	[thread overview]
Message-ID: <20140207115038.GA31250@elgon.mountain> (raw)

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.
