Commit 32726d2d550 ("ARM: SAMSUNG: Remove legacy clock code") already removed the callback pointer, but there was one remaining user: drivers/cpufreq/s3c24xx-cpufreq.c: In function 's3c_cpufreq_resume_clocks': drivers/cpufreq/s3c24xx-cpufreq.c:149:14: error: 'struct s3c_cpufreq_info' has no member named 'resume_clocks' cpu_cur.info->resume_clocks(); ^ Signed-off-by: Arnd Bergmann <arnd@arndb.de> Fixes: 32726d2d550 ("ARM: SAMSUNG: Remove legacy clock code") Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Cc: 3.17+ <stable@vger.kernel.org> # v3.17+ Signed-off-by: Rafael J.
