Some architectures, like arm, do not automatically pull in the definitions for
kzalloc and friends. This allows DAHDI to build on those platforms.

The spi master cur_transfer and cur_msg should only be changed under the
spin_lock for the master. The result is that if running user space tools, like
fxstest, that check registers on the modules, it's possible to have a message
that was not yet complete flagged as completed which would result in a bad read.
This does not affect "normal" operation of the wcaxx driver since interrupts are
not enabled during module detection, and during normal operation all access to
the resgisters is done in the context of the interrupt handler. This would only
be an issue if the interrupt handler was running and register accesses are tried
in user space context on an SMP system.

This is a driver for the new line of analog cards that shares a common interface
with the TE133/TE134 and the TE435.
