From aae9d563230f974f2daa7135f911f021b2bba9e6 Mon Sep 17 00:00:00 2001 From: Christophe Jaillet Date: Fri, 14 Jul 2017 12:06:59 +0200 Subject: [PATCH] iwlwifi: mvm: Fix a memory leak in an error handling path in 'iwl_mvm_sar_get_wgds_table()' We should free 'wgds.pointer' here as done a few lines above in another error handling path. It was allocated within 'acpi_evaluate_object()'.
