From 5f5d03143de5e0c593da4ab18fc6393c2815e108 Mon Sep 17 00:00:00 2001 From: Arend Van Spriel Date: Wed, 26 Jul 2017 13:09:24 +0100 Subject: [PATCH] brcmfmac: fix memleak due to calling brcmf_sdiod_sgtable_alloc() twice Due to a bugfix in wireless tree and the commit mentioned below a merge was needed which went haywire. So the submitted change resulted in the function brcmf_sdiod_sgtable_alloc() being called twice during the probe thus leaking the memory of the first call.
