acer-wmi: Detect communication hot key number
Currently we set a fixed hot key number to 0x01 for communction button, but, actually, the key number is different on each acer laptop and it was reported by SMBIOS. So, add this patch to get the communication hot key number from Acer OEM-specific SMBIOS Type AA. Tested on Acer TravelMate 4750 Cc: Carlos Corbacho <carlos@strangeworlds.co.uk> Cc: Matthew Garrett <mjg@redhat.com> Cc: Dmitry Torokhov <dtor@mail.ru> Cc: Corentin Chary <corentincj@iksaif.net> Cc: Thomas Renninger <trenn@suse.de> Signed-off-by: Lee, Chun-Yi <jlee@suse.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>
