It was this build error on SH (for the second patch):

>> drivers/cpufreq/cpufreq-dt.c:36:29: error: conflicting types for 'cpu_data'
      36 | static struct private_data *cpu_data;

I fixed it by renaming "cpu_data" to "cpufreq_dt_data". (I could not
think of a better name so feel free to use something else...)
