Subject: [ 072/262] ACPI / PM: Use KERN_DEBUG when no power resources are found

From: Greg KH <gregkh@...uxfoundation.org>

3.5-stable review patch.  If anyone has any objections, please let me know.

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

From: Aaron Lu <aaron.lu@...el.com>

commit f25b70613c048ceb1df052576fda03321ebf41cf upstream.

commit a606dac368eed5696fb38e16b1394f1d049c09e9 adds support to link
devices which have _PRx, if a device does not have _PRx, a warning
message will be printed.

This commit is for ZPODD on Intel ZPODD capable platforms, on other
platforms, it has no problem if there is no power resource for this
device, so a warning here is not appropriate, change it to debug.
