6.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Csókás, Bence <csokas.bence@xxxxxxxxx>
[ Upstream commit e96b2933152fd87b6a41765b2f58b158fde855b6 ]
If the module is in SFP_MOD_ERROR, `sfp_sm_mod_remove()` will
not be run. As a consequence, `sfp_hwmon_remove()` is not getting
run either, leaving a stale `hwmon` device behind. `sfp_sm_mod_remove()`
itself checks `sfp->sm_mod_state` anyways, so this check was not
really needed in the first place.
Fixes: d2e816c0293f ("net: sfp: handle module remove outside state machine")
