Git-commit: 34b6cfabd760d3a2784f0ae649eb5e390e0e53cc Patch-mainline: v3.4-rc1 References: bnc#745236 Release-target: openSUSE 12.1 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.
