This is not quite correct, as according to the vendor kernels, msm8976 should use standard slope values (3200), while msm8956 really uses the slope values found in the driver. Add separate compatibility string for msm8956, move slope value overrides to the corresponding init function and use the standard compute_intercept_slope() function for both platforms.
