The functions tegra_machine_get_bclk_ratio() and tegra_machine_get_bclk_ratio_t18x() have a return type of unsigned int but can return a negative error code on failure. This may cause users of this function to get a very large bit clock ratio. Although it is improbable that the bit clock ratio will ever be large enough to overflow a signed integer, it is best to avoid changing the type of the bit clock ratio variable. Therefore, return the bit clock ratio via a pointer passed to the functions tegra_machine_get_bclk_ratio() and tegra_machine_get_bclk_ratio_t18x().
