This would be better handled by using a temporary like:
for (i = 0; i < cmd->chanlist_len; i++) {
<type> list = cmd->chanlist[i];
/* set channel */
bits |= adc_chan_bits(CR_CHAN(list));
/* set gain */
bits |= ai_range_bmts_6xxx(dev, CR_RANGE(list));
/* set single-ended / differential */
bits |= se_diff_bit_6xxx(dev,
CR_AREF(list) ==
AREF_DIFF);
if (CR_AREF(list) == AREF_COMMON)
bits |= ADC_COMMON_BIT;
Or moving the indented block into a separate function.
