Subject: [PATCH drm/hisilicon 1/3] drm/hisilicon: Code refactoring for hibmc_drm_drv
Date: Wed, 2 Dec 2020 16:47:13 +0800 [thread overview]
Message-ID: <1606898835-40775-2-git-send-email-tiantao6@hisilicon.com> (raw)
In-Reply-To: <1606898835-40775-1-git-send-email-tiantao6@hisilicon.com>
Use the devm_drm_dev_alloc provided by the drm framework to alloc
a structure hibmc_drm_private.
