Subject: [PATCH -next 2/5] misc: microchip: pci1xxxx: Fix missing spin_lock_init()
Date: Wed, 7 Sep 2022 08:34:32 +0000 [thread overview]
Message-ID: <20220907083435.1745393-2-weiyongjun@huaweicloud.com> (raw)
In-Reply-To: <20220907083435.1745393-1-weiyongjun@huaweicloud.com>
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.
