Hello Shayne Chen,

The patch 3f0caa3cbf94: "mt76: mt7915: add support for continuous tx in testmode" from Jan 5, 2021, leads to the following static checker warning:

	drivers/net/wireless/mediatek/mt76/mt7915/testmode.c:597 mt7915_tm_set_tx_cont()
	error: uninitialized symbol 'mode'.

586 break;
587 case MT76_TM_TX_MODE_HE_TB:
588 mode = MT_PHY_TYPE_HE_TB;
589 break;
590 case MT76_TM_TX_MODE_HE_MU:
591 mode = MT_PHY_TYPE_HE_MU;

   595          }
   596  
   597          rateval =  mode << 6 | rate_idx;
                           ^^^^^^^^^

   598          tx_cont->rateval = cpu_to_le16(rateval);
