Hi Jack,

With respect to the recent commit in linux-next:

     ASoC: rt721-sdca: Add RT721 SDCA driver


I'm flagging up an issue in function rt721_sdca_dmic_set_gain_get there 
are a bunch of nested if statements as follows:

                 if (!adc_vol_flag) /* boost gain */
                         ctl = regvalue / boost_step;
                 else { /* ADC gain */
                         if (adc_vol_flag)
                                 ctl = p->max - (((vol_max - regvalue) & 
0xffff) / interval_offset);
                         else
                                 ctl = p->max - (((0 - regvalue) & 
0xffff) / interval_offset);
                 }

The last else statement ctl = p->max - (((0 - regvalue) & 0xffff) / 
interval_offset) is redundant, since this is the !adc_vol_flag checked 
for in the first boost gain if clause.
