Subject: [PATCH -next 5/7] drm/virtio: Remove an unnecessary NULL value
Date: Wed, 9 Aug 2023 11:44:43 +0800	[thread overview]
Message-ID: <20230809034445.434902-6-ruanjinjie@huawei.com> (raw)
In-Reply-To: <20230809034445.434902-1-ruanjinjie@huawei.com>

The NULL initialization of the pointer assigned by kzalloc() first is
not necessary, because if the kzalloc() failed, the pointer will be
assigned NULL, otherwise it works as usual. so remove it.
