platform/x86: fujitsu-laptop: model-dependent sparse keymap overrides
Some laptop models need to have different keycodes assigned to hotkey
scancodes. Change the sparse keymap upon a DMI match, before the hotkey
input device is setup.
Instead of using three different callbacks in the DMI match table,
simplify code by using the driver_data field of struct dmi_system_id to
supply the requested keymap to a common callback. Also merge keymaps
for S6410 and S6420 as they are identical.
Rename fujitsu_dmi_table to fujitsu_laptop_dmi_table to emphasize it is
no longer used by the backlight part of fujitsu-laptop. Adjust
whitespace to make checkpatch happy.
