Since it's part of the usual probe -process, all the drivers using that helper will end up having their encoder -and CRTC disable functions called at probe if their device has not been -reported as enabled. - -This could be fixed by reading out from the registers the current state of -the device if it is enabled, but even that will not handle the case where -the device is actually disabled. - -Moreover, the drivers using the atomic modesetting expect that their enable -and disable callback to be called when the device is already enabled or -disabled (respectively). - -We can however fix this issue by moving the call to -drm_helper_disable_unused_functions out of drm_fbdev_cma_init and make the -drivers needing it (all the drivers calling drm_fbdev_cma_init and not -using the atomic modesetting) explicitly call it. - -Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> -Link: http://patchwork.freedesktop.org/patch/msgid/1452785109-6172-14-git-send-email-maxime.ripard@free-electrons.com -Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> -Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> -(cherry picked from commit 4314e19ef4ae0ba8872bd8610f6fef5e8743e236) ---- - drivers/gpu/drm/drm_fb_cma_helper.c | 3 --- - drivers/gpu/drm/imx/imx-drm-core.c | 1 + - drivers/gpu/drm/sti/sti_drv.c | 1 + - drivers/gpu/drm/tilcdc/tilcdc_drv.c | 1 + - 4 files changed, 3 insertions(+), 3 deletions(-) - ---- a/drivers/gpu/drm/drm_fb_cma_helper.c -+++ b/drivers/gpu/drm/drm_fb_cma_helper.c -@@ -348,9 +348,6 @@ struct drm_fbdev_cma *drm_fbdev_cma_init - - } - -- /* disable all the possible outputs/crtcs before entering KMS mode */ -- drm_helper_disable_unused_functions(dev); -- - ret = drm_fb_helper_initial_config(helper, preferred_bpp); - if (ret < 0) { - dev_err(dev->dev, "Failed to set initial hw configuration.\n"); ---- a/drivers/gpu/drm/imx/imx-drm-core.c -+++ b/drivers/gpu/drm/imx/imx-drm-core.c -@@ -313,6 +313,7 @@ static int imx_drm_driver_load(struct dr - dev_warn(drm->dev, "Invalid legacyfb_depth.
