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

wifi: ath12k: fix out-of-bound access of qmi_invoke_handler()

Currently, there is no terminator entry for ath12k_qmi_msg_handlers hence
facing below KASAN warning,

==================================================================
BUG: KASAN: global-out-of-bounds in qmi_invoke_handler+0xa4/0x148

The address belongs to the variable:

[...]
==================================================================

Add a dummy terminator entry at the end to assist the qmi_invoke_handler()
in traversing up to the terminator entry without accessing an
out-of-boundary index.
