From 649f38ae9e482098da94d30f7f802621e66c6b74 Mon Sep 17 00:00:00 2001 From: Hante Meuleman Date: Sun, 25 Jan 2015 20:31:36 +0100 Subject: [PATCH] brcmfmac: Reopen netdev queue on bus state data. During suspend the bus state is put in the down state. When data is being transmitted during this state then the netdev queue will be close. This patch will wake the queue on state data if the queue was closed.
