The APIs read_vin_cal_slope_intercept_fuse() and read_vin_cal_gain_offset_fuse() where prototyped for u32 return types, but they were actually returning negative errno's for errors. Change the return type to int so the errors can be checked properly. clk_vin.c still stores the return values as u32's. This will be fixed in a future patch.
