From 2aac2d8b95923203e683c60124877ab434133679 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 9 Jun 2023 10:15:49 +0200 Subject: [PATCH] clk: samsung: add CONFIG_OF dependency When CONFIG_OF is disabled, build testing on x86 runs into a couple of objtool warnings from functions that unconditionally call panic() but have no __noreturn annotation: vmlinux.o: warning: objtool: exynos3250_cmu_isp_probe+0x17: samsung_cmu_register_one() is missing a __noreturn annotation vmlinux.o: warning: objtool: exynos7885_cmu_probe+0x16: exynos_arm64_register_cmu() is missing a __noreturn annotation vmlinux.o: warning: objtool: exynos850_cmu_probe+0x16: exynos_arm64_register_cmu() is missing a __noreturn annotation vmlinux.o: warning: objtool: exynosautov9_cmu_probe+0x16: exynos_arm64_register_cmu() is missing a __noreturn annotation The objtool analysis is correct, and this could be addressed by just returning success whenever CONFIG_OF is disabled to let all that code be eliminated, but since the driver is no use without CONFIG_OF, just add that as a dependency. It will still get compile tested on all architectures since CONFIG_OF is enabled in allmodconfig and most randconfig builds.
