Making this:

To me this would be cleaner:
mask = config->array[i][gsbi_num - 1];
if (gsbi->mode == GSBI_PRO_SPI)
regmap_update_bits(gsbi->tcsr, TCSR_ADM_CRCI_BASE + i * 4, mask, mask);
else
regmap_update_bits(gsbi->tcsr, TCSR_ADM_CRCI_BASE + i * 4, mask, 0);

There should be an extra set of {} around the if statment body.
