Message-ID: <20100302182943.GK3445@oksana.dev.rtsoft.ru>
Date: Tue, 2 Mar 2010 21:29:43 +0300
From: Anton Vorontsov <avorontsov@...mvista.com>
To: Jeff Garzik <jgarzik@...hat.com>
Cc: linux-ide@...r.kernel.org, linux-kernel@...r.kernel.org
Subject: [PATCH 11/12] ahci: Export generic AHCI symbols
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.
Signed-off-by: Anton Vorontsov <avorontsov@...mvista.com>
