Date: Thu, 14 Feb 2008 13:40:48 +0100 From: Holger Macht <hmacht@...e.de> To: linux-kernel@...r.kernel.org Cc: linux-ide@...r.kernel.org, Tejun Heo <htejun@...il.com>, Kristen Carlson Accardi <kristen.c.accardi@...el.com> Subject: [PATCH] libata: Register for dock events when the drive is inside a dock station If a device/bay is inside a docking station, we need to register for dock events additionally to bay events. If a dock event occurs, the dock driver will call the appropriate handler (ata_acpi_ap_notify() or ata_acpi_dev_notify()) for us.
