[PATCH 1/2] thermal/drivers/iwlwifi: Use generic thermal_zone_get_trip() function

[PATCH 1/2] thermal/drivers/iwlwifi: Use generic thermal_zone_get_trip() function

[Daniel Lezcano]

The thermal framework gives the possibility to register the trip
points with the thermal zone. When that is done, no get_trip_* ops are
needed and they can be removed.

The get_trip_temp, get_trip_hyst and get_trip_type are handled by the
get_trip_point().

The set_trip_temp() generic function does some checks which are no
longer needed in the set_trip_point() ops.

Convert ops content logic into generic trip points and register them
with the thermal zone.

The subject should begin with "wifi: iwlwifi: ".

I don't see patch 2. Via which tree is the plan for this patch?

Gregory, please review this.

patch 2 are similar changes but related to the mellanox driver.

This is the continuation of the trip point rework:

https://lore.kernel.org/netdev/20221003092602.1323944-22-daniel.lezcano@linaro.org/t/

This patch is planned to go through the thermal tree

Sorry I should have mentioned that.

As Kalle commented above, the subject should start with wifi: iwlwifi:
The commit itself seems fine to me.
