For what it's worth, the rename/split is in linux-next, and will land in
3.15 (as part of arm-soc cleanups).

Is the (short-term) problem of the lack of the symbol a problem?  Worse
case, this driver lands before the ARCH_QCOM rename lands, and the
driver is just not selectable.  Only when both are in place can the
driver be selected.
