Subject: [PATCH drm/hisilicon v2 1/4] drm/hisilicon: Assgin local variable to drm_device
Date: Tue, 1 Dec 2020 19:55:51 +0800 [thread overview]
Message-ID: <1606823754-52451-2-git-send-email-tiantao6@hisilicon.com> (raw)
In-Reply-To: <1606823754-52451-1-git-send-email-tiantao6@hisilicon.com>
Assign local variable to struct drm_device *dev because they are
used multiple times within a function.
