From e894536f5e73b741bd55dfe53e864df93532c271 Mon Sep 17 00:00:00 2001 From: Oron Peled Date: Mon, 23 May 2011 19:23:52 +0300 Subject: add to dahdi_device a "hardware_id" attribute as an alternative to "location" - The "hardware_id" does not change with device location (e.g: when a PCI card is moved from one slot to another). - Not all devices have this attribute. It is legal for it to be NULL (that is the default for all low-level drivers that do not set it explicitly). - When "hardware_id" is NULL, the sysfs attribute value is "\n" --- include/dahdi/kernel.h | 13 +++++++++---- 1 file changed, 9 insertions(+), 4 deletions(-) (limited to 'include') diff --git a/include/dahdi/kernel.h b/include/dahdi/kernel.h index d2f3dc7..2ca5acf 100644 --- a/include/dahdi/kernel.h +++ b/include/dahdi/kernel.h @@ -882,17 +882,22 @@ struct dahdi_span_ops { /** * dahdi_device - Represents a device that can contain one or more spans. * - * @spans: List of child spans. + * @spans: List of child spans. * @manufacturer: Device manufacturer. - * @location: The location of this device - * @devicetype: What type of device this is. - * @irqmisses: Count of "interrupt misses" for this device. + * @location: The location of this device.
