From mboxrd@z Thu Jan 1 00:00:00 1970 From: Anton Vorontsov Subject: [PATCH 11/12] ahci: Export generic AHCI symbols Date: Tue, 2 Mar 2010 21:29:43 +0300 Message-ID: <20100302182943.GK3445@oksana.dev.rtsoft.ru> References: <20100302182850.GA32057@oksana.dev.rtsoft.ru> Mime-Version: 1.0 Content-Type: text/plain; charset=utf-8 Return-path: Content-Disposition: inline In-Reply-To: <20100302182850.GA32057@oksana.dev.rtsoft.ru> Sender: linux-kernel-owner@vger.kernel.org To: Jeff Garzik Cc: linux-ide@vger.kernel.org, linux-kernel@vger.kernel.org List-Id: linux-ide@vger.kernel.org This is needed for non-PCI drivers that will be added soon. Since the symbols are exported now, ahci and ahci_pci can be built as a separate modules.
