Subject: PM / Domains: Improve warn for multiple states but no governor
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=46b7fe94995fd166786a301dbba919046e70e702;p=linux.git

PM / Domains: Improve warn for multiple states but no governor

It's possible a PM domain defines only one state and it does not need
a governor to work. For such case, a warning actually is not necessary.
