Currently in the vio.c code we use a comparision against the parent device node's full path to decide if the device is a PFO or VIO family device. Both the ibm,platform-facilities and vdevice nodes are defined by PAPR, and must have a matching device_type. So instead of using the path we can instead compare the device_type. I've checked Qemu and kvmtool both do this correctly, and all the PowerVM systems I have access to do also. So it seems to be safe. This removes the dependency on full_name, which is being removed upstream. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
