From 27c0f739a009971aaf43ee71d9b150a56ee57012 Mon Sep 17 00:00:00 2001 From: Taku Izumi Date: Tue, 10 May 2016 10:28:49 +0900 Subject: [PATCH] fjes: Fix unnecessary spinlock_irqsave commit-bd5a256 introduces a deadlock bug in fjes_change_mtu(). This spin_lock_irqsave() is obviously unnecessary. This patch eliminates unnecessary spin_lock_irqsave() in fjes_change_mtu() Signed-off-by: Taku Izumi Signed-off-by: David S.
