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.

13 Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.5.0.1-01100-QCAHKSWPL_SILICONZ-1
