Subject: thermal: trip: Split thermal_zone_device_set_mode()
X-Git-Tag: v6.11-rc1~24^2~1
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=e5f98896efb3b6350cb6f1c241394966dcbcf240;p=linux-block.git

thermal: trip: Split thermal_zone_device_set_mode()

Pull a wrapper around thermal zone .change_mode() callback out of
thermal_zone_device_set_mode() because it will be used elsewhere
subsequently.

No intentional functional impact.
