Subject: [PATCH -next] thermal: clock_cooling: Fix missing mutex_init()
Date: Mon, 25 Jul 2016 07:01:19 +0000	[thread overview]
Message-ID: <1469430079-8533-1-git-send-email-weiyj.lk@gmail.com> (raw)

The driver allocates the mutex but not initialize it.
Use mutex_init() on it to initialize it correctly.

This is detected by Coccinelle semantic patch.
