Thank you for cleaning this up and improving the docs. From the function name and kerneldoc comment, it was really not clear that this function is already called in the drm_device release path. I think the comment is slightly misleading though, as drm_vblank_cleanup does call kfree(dev->vblank). > Cc: Philipp Zabel <p.za...@pengutronix.de> > Signed-off-by: Daniel Vetter <daniel.vet...@intel.com> > > --- > drivers/gpu/drm/imx/imx-drm-core.c | 4 +--- > 1 file changed, 1 insertion(+), 3 deletions(-) > > diff --git a/drivers/gpu/drm/imx/imx-drm-core.c > b/drivers/gpu/drm/imx/imx-drm-core.c > index 50add2f9e250..95e2181963d9 100644 > --- a/drivers/gpu/drm/imx/imx-drm-core.c > +++ b/drivers/gpu/drm/imx/imx-drm-core.c > @@ -278,7 +278,7 @@ static int imx_drm_bind(struct device *dev) > /* Now try and bind all our sub-components */ > ret = component_bind_all(dev, drm); > if (ret) > - goto err_vblank; > + goto err_kms; > > drm_mode_config_reset(drm); > > @@ -316,8 +316,6 @@ static int imx_drm_bind(struct device *dev) > err_unbind: > #endif > component_unbind_all(drm->dev, drm); > -err_vblank: > - drm_vblank_cleanup(drm); > err_kms: > drm_mode_config_cleanup(drm); > err_unref: As I understand, the drm_dev_unref(drm) that follows this causes drm_dev_release -> drm_dev_fini -> drm_vblank_cleanup to be called, so Acked-by: Philipp Zabel <p.za...@pengutronix.de> regards Philipp _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
