Subject: [PATCH v2 1/6] drm/mgag200: Convert struct drm_device to struct mga_device with helper
Date: Thu,  7 May 2020 11:03:10 +0200	[thread overview]
Message-ID: <20200507090315.21274-2-tzimmermann@suse.de> (raw)
In-Reply-To: <20200507090315.21274-1-tzimmermann@suse.de>

Mgag200 uses dev_private to look up struct mga_device for instances
of struct drm_device. Use of dev_private is deprecated, so hide it in
the helper function to_mga_device().

v2:
	* make to_mga_device() a function (Sam)
