Hi, Dave,

You're right. How about the patch attached?

thanks,

Subject: [PATCH] Thermal: Rename thermal governor Kconfig options

Rename thermal governor Kconfig options,
CONFIG_STEP_WISE, CONFIG_FAIR_SHARE, CONFIG_USER_SPACE
to
CONFIG_THERMAL_GOVERNOR_STEP_WISE,
CONFIG_THERMAL_GOVERNOR_FAIR_SHARE,
CONFIG_THERMAL_GOVERNOR_USER_SPACE,
to avoid confusions brought by the previous generic naming.
