Sean Paul 7a85c86735 drm/msm/dsi: Fix return value check for clk_get_parent ... commit 5fb9b797d5 upstream. clk_get_parent returns an error pointer upon failure, not NULL. So the checks as they exist won't catch a failure. This patch changes the checks and the return values to properly handle an error pointer.
