Subject: crypto: hisilicon/hpre - Use crypto_stdrng_get_bytes()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c30e1bbc9549b39c33f61310302eb8ccb98c7de4;p=thirdparty%2Flinux.git

crypto: hisilicon/hpre - Use crypto_stdrng_get_bytes()

Replace the sequence of crypto_get_default_rng(),
crypto_rng_get_bytes(), and crypto_put_default_rng() with the equivalent
helper function crypto_stdrng_get_bytes().
