[PATCH 0/6] Introduce devm_hwrng_register and convert a few dirvers

[Dmitry Torokhov]

A few drivers can benefit from devm-style interface for hwrng since it
is quite often the last thing that isn't automatically managed. Using
devm_hwrng_register() in such drivers allows get rid of manual error
unwinding and drivers' remove() methods.

I tested changes to iproc-rng200, the rest are compiled only.

Thanks.
