From 34ede45188c318e451ef98183814cc4555208f46 Mon Sep 17 00:00:00 2001 From: Qi Zhang Date: Tue, 2 Mar 2021 15:23:57 +0800 Subject: [PATCH] net/ice/base: cleanup filter list on error When ice_remove_vsi_lkup_fltr is called, by calling ice_add_to_vsi_fltr_list local copy of vsi filter list is created. If any issues during creation of vsi filter list occurs it up for the caller to free already allocated memory. This patch ensures proper memory deallocation in these cases.
