Use more generic functions for finding mac revision instead of pci specific. MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Sender: linux-wireless-owner@vger.kernel.org List-ID: Use ath5k_bus_read_srev as a wrapper for MAC revision register reading. Different buses have to aceess it with own functions before hardware is initialized.
