This patch fixes the below build error reported by Stephen, Stephen reported: After merging the drm-exynos tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/media/i2c/adv7604.o: In function `of_graph_get_endpoint_by_regs': adv7604.c:(.text+0x586c): multiple definition of `of_graph_get_endpoint_by_regs' drivers/media/i2c/adv7343.o:adv7343.c:(.text+0xa13): first defined here drivers/media/platform/soc_camera/atmel-isi.o: In function `of_graph_get_endpoint_by_regs': atmel-isi.c:(.text+0x1ec9): multiple definition of `of_graph_get_endpoint_by_regs' drivers/media/platform/soc_camera/soc_camera.o:soc_camera.c:(.text+0x2ce3): first defined here drivers/media/platform/soc_camera/rcar_vin.o: In function `of_graph_get_endpoint_by_regs': rcar_vin.c:(.text+0x307c): multiple definition of `of_graph_get_endpoint_by_regs' drivers/media/platform/soc_camera/soc_camera.o:soc_camera.c:(.text+0x2ce3): first defined here Caused by commit: a0f7001c18ca ("of: add helper for getting endpoint node of specific identifiers") To fix the error, this patch declares of_graph_get_endpoint_by_regs function with "static inline".
