3.0-stable review patch. If anyone has any objections, please let us know.

From: Yulgon Kim <yulgon.kim@samsung.com>
commit e5d3d4463fb30998385f9e78ab3c7f63b5813000 upstream.
This patch fixes a NULL pointer deference. A NULL pointer dereference happens since s5p_ehci->hcd field is not initialized yet in probe function.
