RE: Bad commit backported on the v5.15.y branch ?

Because it has a "Fixes:" tag on it.  Is that tag not correct?

understood why it's backported. Probably yes. Or maybe another commit should be introduced to not create a new issue.

What "original message"?

My original message in this mailing list, see below commands that show the problem (last line is wrong):

cat /sys/devices/system/cpu/cpufreq/policy0/scaling_available_frequencies 299999 399999 599999 1199999

echo 399999 > /sys/devices/system/cpu/cpufreq/policy0/scaling_setspeed

cat /sys/devices/system/cpu/cpufreq/policy0/scaling_cur_freq 399999

cat /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_cur_freq 299999 ====> Should be 399999
