Subject: s390/delay: sync comment within __delay() with reality
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9aa10e791c2b722cf166f46424a6a8364164fe12;p=linux.git

s390/delay: sync comment within __delay() with reality

The comment within __delay() is outdated and does not reflect anymore
what the function is doing. Therefore replace the comment.
