toshiba_acpi: Add alternative keymap support for Satellite M840
Toshiba Satellite M840 laptop has a complete different keymap although it's bound with the same ACPI ID "TOS1900". This patch provides an alternative keymap specific to this machine by identifying via DMI matching. The keymap table doesn't fill all entries that were used before since some keys aren't found on this machine at all. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=69761 Bugzilla: https://bugzilla.novell.com/show_bug.cgi?id=812209 Reported-and-tested-by: Federico Vecchiarelli <fedev@gmx.net> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
