Re: [PATCH net] net: dsa: b53: fix error propagation from b53_fdb_dump()

Hello:

The blamed commit replaced "return ret" statements in b53_fdb_dump()
with "break;" which jumps to the mutex_unlock() -> return 0 section.

This is notably problematic because it swallows errors from the
b53_fdb_copy() -> cb() path, and this will result in FDB dump truncation
when the netlink skb overflows - see commit 21b52fed928e ("net: dsa:
sja1105: fix broken backpressure in .port_fdb_dump").
