From ec11bb88f977321f117865b4d21079bbacc474ee Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Tue, 27 Oct 2009 12:59:36 -0400 Subject: [PATCH] ath9k_hw: correct AR_PHY_SPECTRAL_SCAN register offset We had 0x9912 but AR_PHY_SPECTRAL_SCAN is 0x9910. By using the 0x9912 we were making the hardware unresponsive. This allows us to move forward with hardware reset on ar9271 on the ath9k_htc driver. Signed-off-by: Luis R.
