Subject: [PATCH -next] pwm: meson: Fix missing spin_lock_init()
Date: Sat, 10 Sep 2016 06:38:38 +0000	[thread overview]
Message-ID: <1473489518-17981-1-git-send-email-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.
