Be more verbose to disambiguate the error case when trying to configure
SRIOV with no driver bound vs. a driver that does not implement the
SRIOV callback.

This patch adds support for the Nios handshake private feature on Intel
PAC (Programmable Acceleration Card) N3000.
The Nios is the embedded processor on the FPGA card. This private feature
provides a handshake interface to FPGA Nios firmware, which receives

This driver is for the EMIF private feature implemented under FPGA
Device Feature List (DFL) framework. It is used to expose memory
interface status information as well as memory clearing control.
The purpose of memory clearing block is to zero out all private memory
when FPGA is
in file2alias.c.

This is a resend of the previous (unfortunately late) patchset of
changes for FPGA DFL.
This contains Matthew's changes to allow for more flexible discovery of
DFLs.
Xu's changeset adds support for DFL device drivers. Two of the first
users are part of the patchset: dfl-emif a memory controller,
