Remove suspend_state from exynos_drm_private struct as it is no more useful. Signed-off-by: Ajit Negi Signed-off-by: Souptick Joarder Tested-by: Marek Szyprowski --- v2: Address Inki Dae's comment. Remove ret variable from both suspend/resume function. v3: Tested by Marek. Updated the change log. v4: removing the return as exynos_drm_resume() now returns void. drivers/gpu/drm/exynos/exynos_drm_drv.c | 26 ++------------------------ drivers/gpu/drm/exynos/exynos_drm_drv.h | 1 - drivers/gpu/drm/exynos/exynos_drm_fbdev.c | 17 ----------------- drivers/gpu/drm/exynos/exynos_drm_fbdev.h | 10 ---------- 4 files changed, 2 insertions(+), 52 deletions(-) diff --git a/drivers/gpu/drm/exynos/exynos_drm_drv.c b/drivers/gpu/drm/exynos/exynos_drm_drv.c index b599f74..6f76baf 100644 --- a/drivers/gpu/drm/exynos/exynos_drm_drv.c +++ b/drivers/gpu/drm/exynos/exynos_drm_drv.c @@ -149,37 +149,15 @@ static void exynos_drm_postclose(struct drm_device *dev, struct drm_file *file) static int exynos_drm_suspend(struct device *dev) { struct drm_device *drm_dev = dev_get_drvdata(dev); - struct exynos_drm_private *private; - - if (!drm_dev) - return 0; - - private = drm_dev->dev_private; - - drm_kms_helper_poll_disable(drm_dev); - exynos_drm_fbdev_suspend(drm_dev); - private->suspend_state = drm_atomic_helper_suspend(drm_dev); - if (IS_ERR(private->suspend_state)) { - exynos_drm_fbdev_resume(drm_dev); - drm_kms_helper_poll_enable(drm_dev); - return PTR_ERR(private->suspend_state); - } - return 0; + return drm_mode_config_helper_suspend(drm_dev); } static void exynos_drm_resume(struct device *dev) { struct drm_device *drm_dev = dev_get_drvdata(dev); - struct exynos_drm_private *private; - - if (!drm_dev) - return; - private = drm_dev->dev_private; - drm_atomic_helper_resume(drm_dev, private->suspend_state); - exynos_drm_fbdev_resume(drm_dev); - drm_kms_helper_poll_enable(drm_dev); + drm_mode_config_helper_resume(drm_dev); } static const struct dev_pm_ops exynos_drm_pm_ops = { diff --git a/drivers/gpu/drm/exynos/exynos_drm_drv.h b/drivers/gpu/drm/exynos/exynos_drm_drv.h index c737c4b..7349e7c 100644 --- a/drivers/gpu/drm/exynos/exynos_drm_drv.h +++ b/drivers/gpu/drm/exynos/exynos_drm_drv.h @@ -195,7 +195,6 @@ struct drm_exynos_file_private { */ struct exynos_drm_private { struct drm_fb_helper *fb_helper; - struct drm_atomic_state *suspend_state; struct device *g2d_dev; struct device *dma_dev; diff --git a/drivers/gpu/drm/exynos/exynos_drm_fbdev.c b/drivers/gpu/drm/exynos/exynos_drm_fbdev.c index 132dd52..918dd2c 100644 --- a/drivers/gpu/drm/exynos/exynos_drm_fbdev.c +++ b/drivers/gpu/drm/exynos/exynos_drm_fbdev.c @@ -270,20 +270,3 @@ void exynos_drm_fbdev_fini(struct drm_device *dev) private->fb_helper = NULL; } -void exynos_drm_fbdev_suspend(struct drm_device *dev) -{ - struct exynos_drm_private *private = dev->dev_private; - - console_lock(); - drm_fb_helper_set_suspend(private->fb_helper, 1); - console_unlock(); -} - -void exynos_drm_fbdev_resume(struct drm_device *dev) -{ - struct exynos_drm_private *private = dev->dev_private; - - console_lock(); - drm_fb_helper_set_suspend(private->fb_helper, 0); - console_unlock(); -} diff --git a/drivers/gpu/drm/exynos/exynos_drm_fbdev.h b/drivers/gpu/drm/exynos/exynos_drm_fbdev.h index b338472..6840b6a 100644 --- a/drivers/gpu/drm/exynos/exynos_drm_fbdev.h +++ b/drivers/gpu/drm/exynos/exynos_drm_fbdev.h @@ -19,8 +19,6 @@ int exynos_drm_fbdev_init(struct drm_device *dev); void exynos_drm_fbdev_fini(struct drm_device *dev); -void exynos_drm_fbdev_suspend(struct drm_device *drm); -void exynos_drm_fbdev_resume(struct drm_device *drm); #else @@ -39,14 +37,6 @@ static inline void exynos_drm_fbdev_restore_mode(struct drm_device *dev) #define exynos_drm_output_poll_changed (NULL) -static inline void exynos_drm_fbdev_suspend(struct drm_device *drm) -{ -} - -static inline void exynos_drm_fbdev_resume(struct drm_device *drm) -{ -} - #endif #endif
