In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt7996: rely on mt76_connac2_mac_tx_rate_val

In order to fix a possible NULL pointer dereference in
mt7996_mac_write_txwi() of vif pointer, export
mt76_connac2_mac_tx_rate_val utility routine and reuse it
in mt7996 driver.
