From: Arnd Bergmann Date: Mon, 11 Sep 2017 20:07:50 +0000 (+0200) Subject: of: provide inline helper for of_find_device_by_node X-Git-Tag: v4.14-rc2~1^2~3 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=aa767cfb75341a6b93742f4d7d1589ac2532c29e;p=platform%2Fkernel%2Flinux-exynos.git of: provide inline helper for of_find_device_by_node The ipmmu-vmsa driver fails in compile-testing on non-OF platforms: drivers/iommu/ipmmu-vmsa.o: In function `ipmmu_of_xlate': ipmmu-vmsa.c:(.text+0x740): undefined reference to `of_find_device_by_node' It would be reasonable to assume that this interface works but returns failure on non-OF builds, like it does on machines that have been booted in another way, so this adds another inline function helper.
