Subject: rust: cpufreq: use `core::ffi::CStr` method names
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=23cd58b1d80364a0dbacf1f8ee5bf1b0aa825be1;p=users%2Fhch%2Fmisc.git

rust: cpufreq: use `core::ffi::CStr` method names

Prepare for `core::ffi::CStr` taking the place of `kernel::str::CStr` by
avoid methods that only exist on the latter.
