    drm/exynos: fix display on issue · 44c91697
    Inki Dae 提交于
    When crtc_funcs->dpms callback is called, exynos_crtc->dpms
    and exynos_encoder->dpms are changed to new mode. But if user
    requests dpms mode operation, OFF -> ON, when crtc's dpms callback
    is called, exynos_encoder->dpms is also changed to ON. This
    makes encoder's dpms callback call be ignored so display power
    couldn't become on again.
    
    This patch removes exynos_encoder->dpms changing and adds 'updated'
    variable to exynos_drm_encoder structure to avoid duplicated overlay
    updating.
