Hello there, I just ran cppcheck over the source code of linux-6.5. It said: linux-6.5/sound/soc/codecs/rt722-sdca.c:612:8: style: Expression is always true because 'else if' condition is opposite to previous condition at line 609. [multiCondition] Source code is 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); } This code might benefit from some rework.
