  - ath9k_htc: fix uninit value bugs Syzbot reported 2 KMSAN bugs in ath9k. All of them are caused by missing
    field initialization. In htc_connect_service() svc_meta_len and pad are not initialized. Based on code it
    looks like in current skb there is no service data, so simply initialize svc_meta_len to 0.
    htc_issue_send() does not initialize htc_frame_hdr::control array. Based on firmware code, it will
    initialize it by itself, so simply zero whole array to make KMSAN happy Fail logs: BUG: KMSAN: kernel-usb-
