[PATCHv2,08/14] Thermal: Make thermal_cdev_update as a global function

Commit Message

[e-mail] Aug. 27, 2012, 4:28 a.m. UTC

This patch makes the thermal_cdev_update function as a
global one, so that other files can use it. This function
serves as a single arbitrator to set the state of a cooling
device.
