Hi Fengguang.

telephony is scheduled for removal one day soon.
Likely no one has a working card.

I presume that's an existing bug in the code that this
change exposed only for x86-64 as there's no failure for
this code x86-32.  Likely too this code never worked for
x86-64.

I presume that line should have been something like this
as otherwise PCIEE_GetSerialNumber is not called.
