   4 Subject: [PATCH] wifi: ath11k: Fix qmi_msg_handler data structure
   5  initialization
   6
   7 qmi_msg_handler is required to be null terminated by QMI module.
   8 There might be a case where a handler for a msg id is not present in the
   9 handlers array which can lead to infinite loop while searching the handler
  10 and therefore out of bound access in qmi_invoke_handler().
  11 Hence update the initialization in qmi_msg_handler data structure.
