Subject: [PATCH -next] [media] rainshadow-cec: Fix missing spin_lock_init()
Date: Tue, 25 Apr 2017 03:12:46 +0000 [thread overview]
Message-ID: <20170425031246.9592-1-weiyj.lk@gmail.com> (raw)
From: Wei Yongjun <weiyongjun1@huawei.com>
The driver allocates the spinlock but not initialize it.
Use spin_lock_init() on it to initialize it correctly.
This is detected by Coccinelle semantic patch.
Fixes: 0f314f6c2e77 ("[media] rainshadow-cec: new RainShadow Tech HDMI
CEC driver")
