lm3630a_bank_a_update_status() and lm3630a_bank_b_update_status() both return the brightness value if the brightness was successfully updated. Writing to these attributes via sysfs would cause a 'Bad address' error to be returned. These functions should return 0 on success, so let's change it to correct that error.
