This avoids a warning as follows during resume: WARNING: CPU: 0 PID: 314 at drivers/gpu/drm/drm_atomic_helper.c:1249 drm_atomic_helper_wait_for_vblanks.part.1+0x284/0x288 [CRTC:28:crtc-0] vblank wait timed out Signed-off-by: Stefan Agner <stefan@xxxxxxxx> --- drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.c b/drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.c index 24f234902646..aeeaf0bcf646 100644 --- a/drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.c +++ b/drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.c @@ -225,9 +225,8 @@ static int fsl_dcu_drm_pm_resume(struct device *dev) fsl_tcon_bypass_enable(fsl_dev->tcon); fsl_dcu_drm_init_planes(fsl_dev->drm); - drm_mode_config_helper_resume(fsl_dev->drm); - enable_irq(fsl_dev->irq); + drm_mode_config_helper_resume(fsl_dev->drm); return 0; } -- 2.14.2 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
