Subject: [PATCH v4 0/4] fujitsu_init() cleanup

These patches should make fujitsu_init() a bit more palatable.  No
changes are made to platform device code yet, for clarity these will be
posted in a separate series after this one gets applied.

Changes from v3:

  - Do not use KBUILD_MODNAME as backlight device name as it breaks
    userspace interface ("fujitsu-laptop" vs. "fujitsu_laptop").

Changes from v2:

  - Patch 2/4 from v2 did not work as expected and was thus replaced
    with a rebased version of patch 3/4 from v1.

  - Added a check in patch 3/4 to prevent a NULL dereference when
    ACPI device FUJ02B1 is not present and ACPI device FUJ02E3 is.

Changes from v1:

  - Rebase on top of reworked Alan Jenkins' cleanup patch series.

  - Drop patch 1/4 from v1 as it has already been applied in reworked
    Alan Jenkins' cleanup patch series.

  - Patch 3/4 from v1 has been replaced with a completely different one
    (patch 2/4).  It needs to be tested on a relevant machine as it is
    based purely on a dump of a DSDT table (further details can be found
    in the patch itself).

  - Patch 3/4 in v2 is a rebased version of patch 8/10 from the reworked
    Alan Jenkins' cleanup patch series.  Patch 2/4 from v2 (the one
    mentioned in the previous bullet point) ensures this one can be
    safely applied without causing a NULL dereference under any
    circumstances.
