Subject: [PATCH] platform/x86: fujitsu-laptop: autodetect LCD interface on all
 models
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Presence of ACPI method SBL2 should be checked on all models rather than
just the ones with predefined hotkey keycode overrides.  Move most of
dmi_check_cb_common() to acpi_fujitsu_bl_add().  Adjust indentation to
make checkpatch happy.
