Subject: [PATCH] iwlwifi: mvm: use FW thermal monitoring regardless of CONFIG_THERMAL
Git-commit: 242d9c8b9a9348ca3226323161b5e837937f830f
Patch-mainline: v5.4-rc1
References: jsc#SLE-13430

It doesn't make sense to use the FW thermal monitoring only if we
have CONFIG_THERMAL, because then we use the default thresholds
etc. which may be different from what the firmware implements, as
we don't maintain them in the driver now. Only the CTDP code needs
to actually be under CONFIG_THERMAL.
