From 968a8ada7e022f85eb51f47a8eb0949149d2d942 Mon Sep 17 00:00:00 2001 From: Arjun Vynipadath Date: Fri, 9 Nov 2018 14:52:01 +0530 Subject: [PATCH] cxgb4vf: fix memleak in mac_hlist initialization [ Upstream commit 24357e06ba511ad874d664d39475dbb01c1ca450 ] mac_hlist was initialized during adapter_up, which will be called every time a vf device is first brought up, or every time when device is brought up again after bringing all devices down. This means our state of previous list is lost, causing a memleak if entries are present in the list. To fix that, move list init to the condition that performs initial one time adapter setup.
