[ Upstream commit 4c2c372de2e108319236203cce6de44d70ae15cd ]
Set the size to 6 instead of 2, since 'para' array is passed to 'rtw_fw_bt_wifi_control(rtwdev, para[0], ¶[1])', which reads 5 bytes:
void rtw_fw_bt_wifi_control(struct rtw_dev *rtwdev, u8 op_code, u8 *data) { ... SET_BT_WIFI_CONTROL_DATA1(h2c_pkt, *data); SET_BT_WIFI_CONTROL_DATA2(h2c_pkt, *(data + 1)); ... SET_BT_WIFI_CONTROL_DATA5(h2c_pkt, *(data + 4));
