[PATCH 5.12 017/178] mlxsw: core: Set thermal zone polling delay argument to real value at init

[Greg Kroah-Hartman]

From: Mykola Kostenok <c_mykolak@xxxxxxxxxx>

[ Upstream commit 2fd8d84ce3095e8a7b5fe96532c91b1b9e07339c ]

Thermal polling delay argument for modules and gearboxes thermal zones
used to be initialized with zero value, while actual delay was used to
be set by mlxsw_thermal_set_mode() by thermal operation callback
set_mode(). After operations set_mode()/get_mode() have been removed by
cited commits, modules and gearboxes thermal zones always have polling
time set to zero and do not perform temperature monitoring.

Set non-zero "polling_delay" in thermal_zone_device_register() routine,
thus, the relevant thermal zones will perform thermal monitoring.

Fixes: 1ee14820fd8e ("thermal: remove get_mode() operation of drivers")
