Subject: [PATCH] staging: octeon: repair "fixed-link" support
From: Alexander Sverdlin <alexander.sverdlin@...ia.com>
The PHYs must be registered once in device probe function, not in device
open callback because it's only possible to register them once.
Fixes: a25e278020 ("staging: octeon: support fixed-link phys")
Signed-off-by: Alexander Sverdlin <alexander.sverdlin@...ia.com>
