From 581e929018ce078d0ce0b02780de2f61e858903b Mon Sep 17 00:00:00 2001 From: Frank Rowand Date: Fri, 2 Mar 2018 20:00:31 -0800 Subject: x86: devicetree: fix config option around x86_flattree_get_config() x86_flattree_get_config() is incorrectly protected by ifdef CONFIG_OF_FLATTREE. It uses of_get_flat_dt_size(), which only exists if CONFIG_OF_EARLY_FLATTREE. This issue has not been exposed previously because OF_FLATTREE did not occur unless it was selected by OF_EARLY_FLATTREE. A devicetree overlay change is selecting OF_FLATTREE directly instead of indirectly enabling it by selecting OF_EARLY_FLATTREE. This problem was exposed by a randconfig generated by the kbuild test robot, where Platform OLPC was enabled. OLPC selects OF_PROMTREE instead of OF_EARLY_FLATREE. The only other x86 platform that selects OF is X86_INTEL_CE, which does select OF_EARLY_FLATTREE.
