[PATCH v2 11/11] platform/x86: fujitsu-laptop: remove redundant fields from struct fujitsu_bl

["Michał Kępień" <kernel@kempniu.pl>]

The dev field of struct fujitsu_bl is assigned in acpi_fujitsu_bl_add(),
but never used afterwards.  brightness_changed is set in get_lcd_level()
and then its value is only printed in a debug message, so it does not
influence execution flow.  Remove both fields as they are redundant.
Update the aforementioned debug message.  Adjust whitespace to make
checkpatch happy.
