The remove callback is only called after probe completed successfully.
In this case platform_set_drvdata() was called with a non-NULL argument
and so ssp is never NULL.
Also note that returning an error code from a remove callback doesn't
result in the device staying bound. It's still removed and devm
callbacks are called. So the memory that ssp pointed to during probe,
goes away without the node being removed from ssp_list. The probable
result of an early exit is accessing freed memory when the list is
walked the next time.

There are two drivers in arch/arm/plat-pxa: mfp and ssp. Both
of them should ideally not be needed at all, as there are
proper subsystems to replace them.
OTOH, they are self-contained and can simply be normal
SoC drivers, so move them over there to eliminate one more
of the plat-* directories.
