Subject: [PATCH net 0/2] fsl/fman: Fix refcount handling of fman-related devices

The series is intended to fix refcount handling for fman-related "struct
device" objects - the devices are not released upon driver removal or in
the error paths during probe. This leads to device reference leaks.

The device pointers are now saved to struct mac_device and properly handled
in the driver's probe and removal functions.

Originally reported by Simon Horman <horms@...nel.org>
(https://lore.kernel.org/all/20240702133651.GK598357@kernel.org/)

Compile tested only.
