libata: report link resume failure as KERN_WARNING instead of ERR
Tejun Heo [Fri, 1 Jul 2011 13:12:09 +0000 (15:12 +0200)]
Link resume failure in itself isn't an error condition and may happen
regularly depending on hardware configuration.  Reporting it as
KERN_ERR makes the condition unnecessarily prominent (e.g. reported
during boot).  Use KERN_WARNING instead.
