Subject: [PATCH RFC 0/5] platform/x86: firmware_attributes_class: Add a
 high level API

Hi all,

These series adds the _long awaited_ API for the Firmware Attributes
class.

You'll find all the details in the commit messages and kernel-doc.

I think it's easier to understand by example, so I used the
samsung-galaxybook driver for this purpose (last patch). IMO code
readibility, simplicity, maintainability, etc. is greatly improved, but
there is still room for improvement of the API itself. For this reason I
submitted this as an RFC.

As always, your feedback is very appreciated :)

Overview
========

Patch 1-2: New API with docs included.
  Patch 3: New firwmare attributes type
  Patch 4: Misc Maintainers patch
  Patch 5: samsung-galaxybook example
