Piyush Shah	388f4fd7ef	wifi_provisioning: Add a check for number of scanned networks while allocating memory ... If number of scanned networks is zero, while getting the list, since we try to allocate zero bytes, we get a NULL pointer in response. This is considered as an error and the provisioning worflow breaks there. Adding a check before allocation resolves the issue.	2021-01-15 05:01:35 +00:00
