MSM_BUS_SCALING is not defined in Kconfig, so the code in this #ifdef block won't be compiled at its current state. I saw some references on this Kconfig option in other files; is there a reason for the absence of MSM_BUS_SCALING? I found this issue with ./scripts/checkkconfigsymbols.py by diffing yesterday's and today's next tree. Kind regards, Valentin
