Subject: [PATCH v2 0/2] cpufreq: cleanups and minor fixes

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) The second patch is new in this version. It simplifies the validation
     logic in cpufreq_register_driver().This makes the registration code 
     more straightforward without changing functionality.

Changes since v1:
	- Dropped the second patch from v1, which was not needed.
	- Kept the first patch as-is (already Acked).
	- Added a new second patch to simplify driver registration checks

Zihuan Zhang (2):
  cpufreq: use strlen() for governor name comparison
  cpufreq: simplify setpolicy/target check in driver verification
