Subject: [PATCH] net: stmmac: Fix missing spin_lock_init in visconti_eth_dwmac_probe()
Date: Tue, 23 Feb 2021 10:48:03 +0000	[thread overview]
Message-ID: <20210223104803.4047281-1-weiyongjun1@huawei.com> (raw)

The driver allocates the spinlock but not initialize it.
Use spin_lock_init() on it to initialize it correctly.

Fixes: b38dd98ff8d0 ("net: stmmac: Add Toshiba Visconti SoCs glue driver")
Reported-by: Hulk Robot <hulkci@huawei.com>
