Subject: [PATCH 21/25] drm: kirin: Fix dev->driver_data setting
Date: Tue, 23 Apr 2019 16:20:52 -0700	[thread overview]
Message-ID: <1556061656-1733-22-git-send-email-john.stultz@linaro.org> (raw)
In-Reply-To: <1556061656-1733-1-git-send-email-john.stultz@linaro.org>

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch changes the
dev->driver_data to point to a drm_device, not ade_data.

Thus we set the driver data to drm device after alloc.
