Thomas Renninger 8dda6b0410 x86 platform drivers: hp-wmi fix buffer size depending on ACPI version ... Depending on ACPI version (1.0 -> 32 bit) an integer could be 32 or 64 bit long. _WED internal concatenates two integers and the return value will be 8 byte (2* 32 bit) or 16 byte (2* 64 bit) long, depending on the ACPI version. Also the data send with the WMI event is defined to be splitted into: - Event ID -> 4 bytes - Event Data -> 4 bytes This gets messed up with new ACPI versions. But it's a HP BIOS bug that may get fixed in the future -> Support both, 16 and 8 byte _WED buffers. Also the wrong assumption that from the event data sent, only the first byte is relevant got cleaned up that it fits event_id/event_data as described above.
