local variable "rc" is not used. It is safe to remove and There is only one caller of libipw_qos_convert_ac_to_parameters(). hence make it void Signed-off-by: zhong jiang <zhongjiang@xxxxxxxxxx> --- drivers/net/wireless/intel/ipw2x00/libipw_rx.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) diff --git a/drivers/net/wireless/intel/ipw2x00/libipw_rx.c b/drivers/net/wireless/intel/ipw2x00/libipw_rx.c index 34cfd81..0cb36d1 100644 --- a/drivers/net/wireless/intel/ipw2x00/libipw_rx.c +++ b/drivers/net/wireless/intel/ipw2x00/libipw_rx.c @@ -999,13 +999,12 @@ static int libipw_read_qos_info_element(struct /* * Write QoS parameters from the ac parameters. */ -static int libipw_qos_convert_ac_to_parameters(struct +static void libipw_qos_convert_ac_to_parameters(struct libipw_qos_parameter_info *param_elm, struct libipw_qos_parameters *qos_param) { - int rc = 0; int i; struct libipw_qos_ac_parameter *ac_params; u32 txop; @@ -1030,7 +1029,6 @@ static int libipw_qos_convert_ac_to_parameters(struct txop = le16_to_cpu(ac_params->tx_op_limit) * 32; qos_param->tx_op_limit[i] = cpu_to_le16(txop); } - return rc; } /* -- 1.7.12.4
