Subject: [PATCH -next] media: platform: Fix missing spin_lock_init()
Date: Mon, 17 Dec 2018 12:14:35 +0000	[thread overview]
Message-ID: <1545048875-157403-1-git-send-email-weiyongjun1@huawei.com> (raw)

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: d2b4387f3bdf ("media: platform: Add Aspeed Video Engine driver")
