[06/35] x86, intel, power: Correct the MSR_IA32_ENERGY_PERF_BIAS message

[Greg KH]

3.0-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Len Brown <len.brown@xxxxxxxxx>

commit 17edf2d79f1ea6dfdb4c444801d928953b9f98d6 upstream.

Fix the printk_once() so that it actually prints (didn't print before
due to a stray comma.)

[ hpa: changed to an incremental patch and adjusted the description
  accordingly. ]
