drm/sti: Depend on OF rather than selecting it Commit cc6b741c6f63 ("drm: sti: remove useless fields from vtg structure") reworked some code inside of this driver and made it select CONFIG_OF. This results in the entire OF layer being enabled when building an allmodconfig on ia64. OF on ia64 is completely unsupported so this isn't a great state of affairs. The 0day robot noticed a link-time failure on ia64 caused by using of_node_to_nid() in an otherwise unrelated driver. The generic fallback for of_node_to_nid() only exists when: defined(CONFIG_OF) && defined(CONFIG_NUMA) == false Since CONFIG_NUMA is usually selected for IA64 we get the link failure. Fix this by making the driver depend on OF rather than selecting it, odds are that was the original intent.
