Xiang Yang 281df5e1a6 drm/exynos: fix a potential error pointer dereference 
[ Upstream commit 73bf1c9ae6c054c53b8e84452c5e46f86dd28246 ]

Smatch reports the warning below:
drivers/gpu/drm/exynos/exynos_hdmi.c:1864 hdmi_bind()
error: 'crtc' dereferencing possible ERR_PTR()

The return value of exynos_drm_crtc_get_by_type maybe ERR_PTR(-ENODEV),
which can not be used directly. Fix this by checking the return value
before using it.
