drivers/net/wireless/rtlwifi/rtl8192ce/trx.c:255:5: warning: ‘rf_rx_num’ may be used uninitialized in this function
drivers/net/wireless/rtlwifi/rtl8192ce/trx.c:257:12: warning: ‘total_rssi’ may be used uninitialized in this function
drivers/net/wireless/rtlwifi/rtl8192ce/trx.c:466:6: warning: ‘weighting’ may be used uninitialized in this function
