cpufreq: exynos: Fix the compile error
Commit 7da83a80 ("ARM: EXYNOS: Migrate Exynos specific macros from plat to mach") which lands in samsung tree causes build breakage for cpufreq-exynos like following: drivers/cpufreq/exynos-cpufreq.c: In function 'exynos_cpufreq_probe': drivers/cpufreq/exynos-cpufreq.c:166:2: error: implicit declaration of function 'soc_is_exynos4210' [-Werror=implicit-function-declaration] drivers/cpufreq/exynos-cpufreq.c:168:2: error: implicit declaration of function 'soc_is_exynos4212' [-Werror=implicit-function-declaration] drivers/cpufreq/exynos-cpufreq.c:168:2: error: implicit declaration of function 'soc_is_exynos4412' [-Werror=implicit-function-declaration] drivers/cpufreq/exynos-cpufreq.c:170:2: error: implicit declaration of function 'soc_is_exynos5250' [-Werror=implicit-function-declaration] cc1: some warnings being treated as errors make[2]: *** [drivers/cpufreq/exynos-cpufreq.o] Error 1 make[2]: *** Waiting for unfinished jobs.... drivers/cpufreq/exynos4x12-cpufreq.c: In function 'exynos4x12_set_clkdiv': drivers/cpufreq/exynos4x12-cpufreq.c:118:2: error: implicit declaration of function 'soc_is_exynos4212' [-Werror=implicit-function-declaration] cc1: some warnings being treated as errors make[2]: *** [drivers/cpufreq/exynos4x12-cpufreq.o] Error 1 make[1]: *** [drivers/cpufreq] Error 2 This fixes above error with getting SoC information via of_machine_is_compatible() instead of soc_is_exynosXXXX().
