Subject: [PATCH v1 6/9] iwlwifi: mvm: Set THERMAL_TRIP_WRITABLE_TEMP directly

From: "Rafael J. Wysocki" <[email-masked]>
Date: Fri, 09 Feb 2024 15:10:24 +0100

From: Rafael J. Wysocki <[email-masked]>

It is now possible to flag trip points with THERMAL_TRIP_WRITABLE_TEMP
to allow their temperature to be set from user space via sysfs instead
of using a nonzero writable trips mask during thermal zone registration,
so make the iwlwifi code do that.

No intentional functional impact.

Note that this change is requisite for dropping the mask argument from
thermal_zone_device_register_with_trips() going forward.

This patch obviously depends on

https://patchwork.kernel.org/project/linux-pm/patch/8346768.T7Z3S40VBb@kreacher/

which has been queued up for 6.9 already.
