From: Maarten Lankhorst Date: Thu, 4 Oct 2018 09:46:01 +0000 (+0200) Subject: drm/i915: Use crtc->state in intel_fbdev_init_bios X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=6e3d9dd0ae0aa4f0b6ccb273aa88c2e19e901cce;p=openwrt%2Fstaging%2Fblogic.git drm/i915: Use crtc->state in intel_fbdev_init_bios fbdev init shouldn't race with userspace since it's called from intel_modeset_init, so it's safe to dereference crtc->state and assume nothing changed yet. At least not more harmful than crtc->config.
