Subject: [PATCH net-next v2 2/5] mlxsw: core: fix mlxsw_devlink_info_get() to correctly report driver name
Currently, mlxsw_devlink_info_get() reports the device_kind. The
device_kind is not necessarily the same as the device_name. For
example, the mlxsw_i2c implementation sets up the device_kind as
ic2_client::name in [1] which indicates the type of the device
(e.g. chip name).
Fix it so that it correctly reports the driver name.

Fixes: a9c8336f6544 ("mlxsw: core: Add support for devlink info command")
