[PATCH net-next v2 1/5] mlxsw: minimal: fix mlxsw_m_module_get_drvinfo() to correctly report driver name

[Vincent Mailhol]

Currently, mlxsw_m_module_get_drvinfo() 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), not the actual driver name.

Fix it so that it correctly reports the driver name.
