Just to clarify, what you're objecting to is effectively the
following? Because it is not guaranteed in the future that the probe
order will be the same as the platform_driver_register() calls?
static int __init exynos_drm_init(void)
{
ret = platform_driver_register(&hdmi_driver);
if (ret < 0)
goto out_hdmi;
ret = platform_driver_register(&mixer_driver);
if (ret < 0)
goto out_mixer;
ret = platform_driver_register(&exynos_drm_common_hdmi_driver);
if (ret < 0)
goto out_common_hdmi;
ret = platform_driver_register(&exynos_drm_platform_driver);
if (ret < 0)
goto out_drm;
(exynos_drm_platform_driver is the driver that creates the drm_device)
Thanks
Daniel
