From: Thierry Reding Date: Thu, 22 May 2014 07:57:15 +0000 (+0200) Subject: drm/tegra: Remove host1x drm_bus implementation X-Git-Tag: firefly_0821_release~176^2~3773^2~9^2~15 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=9910f5c455de10f0eb2559093a7adad65f6c05cd;p=firefly-linux-kernel-4.4.55.git drm/tegra: Remove host1x drm_bus implementation The DRM core can now cope with drivers that don't have an associated struct drm_bus, so the host1x implementation is no longer useful.
