Subject: [PATCH net-next 1/6] eth: fbnic: move sensor read logic out of fbnic_mac
Date: Tue, 21 Jul 2026 15:15:35 -0700 [thread overview]
Message-ID: <20260721221540.648272-2-limzhineng2@gmail.com> (raw)
In-Reply-To: <20260721221540.648272-1-limzhineng2@gmail.com>
The sensor read lived behind the fbnic_mac get_sensor op, but it is only
ever used by the hwmon subsystem. Move the read into fbnic_hwmon.c and
call it directly there, closer to where it is used, and drop the
now-unused get_sensor op from struct fbnic_mac. No functional change.
