Considerations

In the cmos_get_isp_default function, assign a default value to exp_ratio based on the WDR mode. The assigned value must be consistent with the exposure ratio initialized by the AE in the cmos_get_ae_default.

• If ae_sns_dft->man_ratio_enable is set to TRUE, the values of exp_ratio and ae_sns_dft->arr_ratio are the same.
• If ae_sns_dft->man_ratio_enable is FALSE, exp_ratio is 0x40.
