This series fixes several bugs in qcom-rng, including failure to enable
the clock before accessing the hardware, generating biased random
numbers, and generating duplicate or non-random numbers due to missing
locking.  To fix the latter bug, it drops the support for the
duplicative crypto_rng interface, which isn't used in practice, leaving
just hwrng which is the one that actually matters.

This series is targeting cryptodev/master

Eric Biggers (4):
  crypto: qcom-rng - Enable clock in hwrng case
  crypto: qcom-rng - Allow zero as a random number
  crypto: qcom-rng - Remove crypto_rng interface
  hwrng: qcom - Move qcom-rng.c into drivers/char/hw_random/
