[PATCH] drm: of: Fix linking when CONFIG_OF is not set

Biju Das <biju.das.jz@...>

From: Laurent Pinchart <laurent.pinchart+renesas@...>

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.

Fixes: 6529007522de ("drm: of: Add drm_of_lvds_get_dual_link_pixel_order")
