[PATCH 1/8] cppc_cpufreq: fix misspelling, code style and readability issues

From: Ionela Voinescu
Date: Thu Nov 05 2020 - 07:56:44 EST


Fix a few trivial issues in the cppc_cpufreq driver:

- indentation of function arguments
- consistent use of tabs (vs space) in defines
- spelling: s/Offest/Offset, s/trasition/transition
- order of local variables, from long pointers to structures to
short ret and i (index) variables, to improve readability
