Subject: crypto: skcipher - remove redundant check for SKCIPHER_WALK_SLOW
X-Git-Tag: v6.14-rc1~112^2~12
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=24300d282f7e60ee407c7a6ec8e316b8b9fd570d;p=thirdparty%2Fkernel%2Fstable.git

crypto: skcipher - remove redundant check for SKCIPHER_WALK_SLOW

In skcipher_walk_done(), remove the check for SKCIPHER_WALK_SLOW because
it is always true.  All other flags (and lack thereof) were checked
earlier in the function, leaving SKCIPHER_WALK_SLOW as the only
remaining possibility.
