[PATCH 0/2] cpufreq: minor cleanups around policy parsing and API

[Zihuan Zhang]

This series contains two small cpufreq cleanups:

  1) Use strlen() as the length argument for strncasecmp() in
     cpufreq_parse_policy(). This makes comparison more permissive
     (prefix match), which is consistent with the intention in our
     deployment and improves readability over using CPUFREQ_NAME_LEN.

  2) Drop the redundant `new_pol` parameter from cpufreq_set_policy().
     Only drivers that implement ->setpolicy would ever care about
     policy values, and passing `new_pol` around is unnecessary.
     Callers now pass just the policy and (where applicable) the
     governor pointer; drivers can read policy->policy directly.

No functional regressions are expected for drivers which do not
implement ->setpolicy (e.g. acpi-cpufreq), as they ignore policy
values anyway.

Zihuan Zhang (2):
  cpufreq: use strlen() for governor name comparison
  cpufreq: simplify cpufreq_set_policy() interface
