From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ivo van Doorn Subject: [PATCH] rt2x00 eeprom_93cx6 split Date: Sun, 10 Dec 2006 14:18:15 +0100 Message-ID: <200612101418.16141.IvDoorn@gmail.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Cc: netdev@vger.kernel.org, Michael Wu Return-path: Received: from nf-out-0910.google.com ([64.233.182.185]:7189 "EHLO nf-out-0910.google.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1760571AbWLJNS1 (ORCPT ); Sun, 10 Dec 2006 08:18:27 -0500 Received: by nf-out-0910.google.com with SMTP id o25so1690020nfa for ; Sun, 10 Dec 2006 05:18:25 -0800 (PST) To: "John W. Linville" Content-Disposition: inline Sender: netdev-owner@vger.kernel.org List-Id: netdev.vger.kernel.org This patch will move the eeprom_93cx6 module out of the rt2x00 and into the /lib folder. This will allow adm80211 driver to use the module as well. This will also make sure the read_opcode and the word index are written to the chip in a single command.
