drm/i915: Restore the KMS modeset for every activated CRTC
Restore the modeset for every activated CRTC in course of resume. This is realized by calling the function of drm_helper_resume_force_mode. Note: it is meaningful only for the KMS mode. https://bugs.freedesktop.org/show_bug.cgi?id=21719 https://bugs.freedesktop.org/show_bug.cgi?id=21708 https://bugs.freedesktop.org/show_bug.cgi?id=22285 https://bugs.freedesktop.org/show_bug.cgi?id=22263 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Eric Anholt <eric@anholt.net>
