- Add #ifdef CONFIG_TEMP_SENSOR before #include'ing temp_sensor.h which actually requires temp_sensor_id to be defined. Revert the forward declare used earlier since it is not the correct solution in this case. - Add #ifdef CONFIG_CHARGER before calling charger_init() Signed-off-by: David Hendricks <dhendrix@chromium.org> BUG=None TEST=compiled on both BDS and Discovery Change-Id: I60b7e4ba91eb958b3ad724cc9ffa9a12fe9c3a71
