Check for EPROBE_DEFER instead of silently not using icc if the msm driver probes before the interconnect driver.

Agreed with supporting deferred ICC probing.

Only check for EPROBE_DEFER because of_icc_get can return other errors that we want to ignore (ENODATA).

What would be the -ENODATA case?

If the 'interconnects' property is not specified of_icc_get() returns NULL, shouldn't all (or most) errors be propagated rather than staying silent?

Thanks
