Subject: [PATCH 07/20] drm/hisilicon: Don't set drm_device->platformdev
Date: Tue,  9 Aug 2016 15:41:18 +0200	[thread overview]
Message-ID: <1470750091-16627-8-git-send-email-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <1470750091-16627-1-git-send-email-daniel.vetter@ffwll.ch>

It's deprecated and only should be used by drivers which still use
drm_platform_init, not by anyone else.

And indeed it's entirely unused and can be nuked.

This required a bit more fudging, but I guess kirin_dc_ops really
wants to operate on the platform_device, not something else. Also
bonus points for implementing abstraction, and then storing the vfunc
in a global variable.
