Subject: [PATCH] ath9k_hw: remove some useless calibration data
Content-Type: text/plain; charset=ISO-8859-1
Sender: linux-wireless-owner@vger.kernel.org
List-ID: <linux-wireless.vger.kernel.org>

The percal struct and bitmask for the initial DC calibration are not
used anywhere, so they can be removed.
