Subject: [PATCH net-next v4 09/27] net: pse-pd: Remove is_enabled callback
from drivers
From: Kory Maincent (Dent Project) <kory.maincent@...tlin.com>
The is_enabled callback is now redundant as the admin_state can be obtained
directly from the driver and provides the same information.
To simplify functionality, the core will handle this internally, making
the is_enabled callback unnecessary at the driver level. This patch
removes the callback from all drivers.
Signed-off-by: Kory Maincent <kory.maincent@...tlin.com>
