Summary

Create pcib_request_feature to allow drivers to request
the firmware (ACPI) release certain features it may be using. ACPI normally
manages things like hot plug, advanced error reporting and other features and
the OS must request ACPI relenquish that use before it can use them.

The default kobjmethod already fails with ENXIO, so I think you don't need this.

Log:

Create pcib_request_feature.

pcib_request_feature allows drivers to request the firmware (ACPI)
release certain features it may be using. ACPI normally manages things
like hot plug, advanced error reporting and other features until the
OS requests ACPI to relenquish control since it is taking over.
