Subject: [PATCH] net: sfp: fix hwmon
|
|
|
|
The referenced commit below allowed more than one hwmon device to be
|
|
created per SFP, which is definitely not what we want. Avoid this by
|
|
only creating the hwmon device just as we transition to WAITDEV state.
|
|
|
|
Fixes: 139d3a212a1f ("net: sfp: allow modules with slow diagnostics to probe")
