If the probe fails, the ci13xxx_add_device will not return error,

therefore, the platform layer can't know whether core's probe
is successful or not, if platform layer goes on using core's struct
which is initialized at core's probe, the error will occur.

This error is showed when I only compile gadget, the host-only
controller reports "no supported roles", and fails probe, but imx
platform code doesn't know it, and goes on using core's private data.

this just tells you that platform code shouldn't be using the driver
directly. passing probe_retval via platform_data is an abomination, fix
the real problem instead, whatever it is.
