Hi, Myron
Now the IPMI interface defined in ACPI namespace is detected by using
PNP device driver. But it seems that this still belongs to ACPI
detection mechanism. At the same time IPMI device defined in ACPI
namespace is also used to enable the communication between ACPI and IPMI
device. In such case it will be better to know whether the IPMI
interface is discovered by using ACPI detection mechanism , which can be
realized by comparing the info->dev with acpi_dev->dev.
Can we still use the acpi_dev->dev to track the IPMI device
discovery?
thanks.
