Wysocki <rafael.j.wysocki@xxxxxxxxx> The DRM driver creates the HDMI codec but its registration fails, due to some missing clocks. The clock are missing because the exynos5-subcmu driver probing fails. [ 0.678578] exynos5-subcmu: probe of GSC failed with error -17 [ 0.679250] exynos5-subcmu: probe of MFC failed with error -17 [ 0.679992] exynos5-subcmu: probe of DISP failed with error -17 The exynos5-subcmu driver before registering platform device makes of_genpd_add_device() call, so in platform_drv_probe() dev_pm_domain_attach() call will fail, as dev->pm_domain is already set. Previously the error was masked by code removed in the above commit and platform_drv_probe() was could complete successfully. -- Regards, Sylwester -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
