Subject: [PATCH v2 0/2] hwrng: st - fix potential race condition

Fix a potential race condition in the st-rng driver. There's a short timeframe
where the driver is still registered but its peripheral clock is disabled.

Add support for compile-testing the driver. I do not have any hardware that
supports st-rng.

v2: Remove some more obsolete code and rephrase the explanation. The point is
    that devres does now disable the clock.

Martin Kaiser (2):
  hwrng: st - support compile-testing
  hwrng: st - keep clock enabled while hwrng is registered
