From d72007751cc60eb97b2a267255cf804f5327a40a Mon Sep 17 00:00:00 2001 From: Alan Chen Date: Fri, 22 May 2020 12:36:46 -0700 Subject: [PATCH] qcacld-3.0: Add connection check before dhcp protection Add connection check in set_power_mgmt() before enabling dhcp protection since set_power_mgmt() can be called in disconnected state as well for enabling power save.
