From ed3725e15a154ebebf44e0c34806c57525483f92 Mon Sep 17 00:00:00 2001 From: Rahul Bhattacharjee Date: Fri, 21 Oct 2022 14:31:26 +0530 Subject: [PATCH] wifi: ath11k: Fix qmi_msg_handler data structure initialization qmi_msg_handler is required to be null terminated by QMI module. There might be a case where a handler for a msg id is not present in the handlers array which can lead to infinite loop while searching the handler and therefore out of bound access in qmi_invoke_handler(). Hence update the initialization in qmi_msg_handler data structure.
