Subject: [PATCH net-next 5/9] mlxsw: core_hwmon: Introduce slot parameter in hwmon interfaces
From: Vadim Pasternak <vadimp@...dia.com>
Add 'slot' parameter to 'mlxsw_hwmon_dev' structure. Use this parameter
in mlxsw_reg_mtmp_pack(), mlxsw_reg_mtbr_pack(), mlxsw_reg_mgpir_pack()
and mlxsw_reg_mtmp_slot_index_set() routines.
For main board it'll always be zero, for line cards it'll be set to
the physical slot number in modular systems.
