hwrng: Pass entropy to add_hwgenerator_randomness() in bits, not bytes
rng_get_data() returns the number of bytes read from the hardware. The entropy argument to add_hwgenerator_randomness() is passed directly to credit_entropy_bits() so we should be passing the number of bits, not bytes here. Fixes: be4000bc464 "hwrng: create filler thread" Acked-by: Torsten Duwe <duwe@suse.de> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
