Just for safety, since handle 0x0000 is a valid handle [1] it would
be better to initialize it to an invalid value.
0x0 is not valid, it's just the lack of a value.
But you can use it. "Just for safety" we'd better set to an invalid
value that cannot be used by the acpi methods.

sony_laptop: found handle 0x0000 (offset: 0x0d)
sony_laptop: called SN07 with 0x000d (result: 0x0000)
this is only going through the handles buffer and telling you that at
0x0d there is nothing.
the calling code:
ret = sony_call_snc_handle(0, 0, &result);
it returns 0.
sony_find_snc_handle should return -1 when called with handle == -1, right?
