From: Daniel Vetter Date: Wed, 15 Apr 2020 07:39:59 +0000 (+0200) Subject: drm/tidss: Don't use drm_device->dev_private X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=02bb1317d5e4002e65a3debfb27ae2a1bfd0a3c2;p=uclinux-h8%2Flinux.git drm/tidss: Don't use drm_device->dev_private Upcasting using a container_of macro is more typesafe, faster and easier for the compiler to optimize.
