Subject: net: tipc: Use crypto_stdrng_get_bytes()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=117c3c4df23d973357a523f6dce1f63d28bbf8aa;p=thirdparty%2Fkernel%2Flinux.git

net: tipc: 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().
