From: Laurent Pinchart commit 528d06d41b80a4acb2a9efd33bfc87495147f75e upstream. The new helper drm_of_lvds_get_dual_link_pixel_order() introduced in commit 6529007522de has a fallback stub when CONFIG_OF is not set, but the stub is declared in drm_of.h without a static inline. This causes multiple definitions of the function to be linked when the CONFIG_OF option isn't set. Fix it by making the stub static inline.
