+ pdx86 ML and Mario.

This driver was only recently made functional due to fixing an 
capitalization issue in its ID.  Mario has been fixing empty attribute 
(and other) problems since then:

releases/6.18.4/platform-x86-hp-bioscfg-fix-out-of-bounds-array-acce.patch
releases/6.18.8/platform-x86-hp-bioscfg-fix-automatic-module-loading.patch
releases/6.18.8/platform-x86-hp-bioscfg-fix-kernel-panic-in-get_instance_id-macro.patch
releases/6.18.8/platform-x86-hp-bioscfg-fix-kobject-warnings-for-empty-attribute-names.patch
releases/6.18.10/platform-x86-hp-bioscfg-skip-empty-attribute-names.patch

It might be worth trying 6.18.10+ as 6.18.9 is missing that last empty 
attribute fix.

Hi Ilpo.
Thanks. I can confirm that these messages are gone when using 6.18.13. Sorry
about the false alarm.

Kind regards,
Daniel

No problem at all. Thanks for testing!
