Laurentiu Tudor 5bd9dc3e76 bus: fsl-mc: don't assume child devices are all fsl-mc devices ... [ Upstream commit 303c9c63ab ] Changes in VFIO caused a pseudo-device to be created as child of fsl-mc devices causing a crash [1] when trying to bind a fsl-mc device to VFIO. Fix this by checking the device type when enumerating fsl-mc child devices.
