Subject: selftests: cpufreq: conform test to TAP
X-Git-Tag: io_uring-6.10-20240523~109^2~24
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=c7e84706fd3be0b56ae23c6a8930a9e5615a869a;p=linux-2.6-block.git

selftests: cpufreq: conform test to TAP

This test outputs lots of information. Let's conform the core part of
the test to TAP and leave the information printing messages for now.
Include ktap_helpers.sh to print conformed logs. Use KSFT_* macros to
return the correct exit code for the kselftest framework and CIs to
understand the exit status.
