From: Daniel Vetter Date: Tue, 3 Jul 2012 11:19:00 +0000 (+0200) Subject: drm/i915: rip out intel_crtc->dpms_mode X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=84bb65bded92028a6c803fef332586fedbe092b2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: rip out intel_crtc->dpms_mode Afaict this has been used for two things: - To prevent the crtc enable code from being run twice. We have now intel_crtc->active to track this in a more precise way. - To ensure the code copes correctly with the unknown hw state after boot and resume. Thanks to the hw state readout and sanitize code we have now a better way to handle this. The only thing it still does is complicate our modeset state space. Having outlived its usefullness, let it just die.
