I see same error message in dmesg with kernel 3.11-rc5 when my notebook is
suspending or hibernating. But suspend and hibernate working fine. I have
Radeon HD 6470M card.

This is printed with my Barts GPU as well, which seems to indicate that the
function is slightly misnamed.

Bug still persist in  3.18.1 kernel. And it's very annoying, because in my
laptop(Radeon HD5400) I cannot return from suspend/hibernate because of this
bug, and I need to restart computer...

The code is shared across several generations of hardware.  As long as suspend
and resume works ok, it can be ignored.
