Hi Chanwoo, your commit 96bd6224f07b ("clk: samsung: exynos5433: Add clocks using common clock framework") is included in today's linux-next tree (i.e., next-20150310). This patch conditionally compiles clk-exynos5433.c depending on the Kconfig option ARCH_EXYNOS5433. However, this option is not defined in Kconfig, so that the driver cannot be compiled at the current state: +obj-$(CONFIG_ARCH_EXYNOS5433) += clk-exynos5433.o Is there a patch queued somewhere that adds this Kconfig symbol? I detected the issue by running undertaker-checkpatch from the Undertaker tool suite (undertaker.cs.fau.de). There is also a tool in the git tree that can detect such issues (i.e., scripts/checkkconfigsymbols.py).
