[PATCH net v2] net: dsa: felix: suppress -EPROBE_DEFER errors

From: Michael Walle
Date: Fri Apr 08 2022 - 06:16:05 EST


The DSA master might not have been probed yet in which case the probe of
the felix switch fails with -EPROBE_DEFER:
[ 4.435305] mscc_felix 0000:00:00.5: Failed to register DSA switch: -517

It is not an error. Use dev_err_probe() to demote this particular error
to a debug message.

Fixes: 56051948773e ("net: dsa: ocelot: add driver for Felix switch family")

changes since v1:
- add Fixes tag and thus use net instead of net-next
- just replace this particular dev_err() with dev_err_probed()
- reword commit message
