Subject: [PATCH -next 2/7] drm/amd/display: Remove unnecessary NULL values
Date: Wed, 9 Aug 2023 11:44:40 +0800	[thread overview]
Message-ID: <20230809034445.434902-3-ruanjinjie@huawei.com> (raw)
In-Reply-To: <20230809034445.434902-1-ruanjinjie@huawei.com>

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