Subject: crypto: algboss - remove redundant setting of len to zero
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e781c17c22fdd390e54b972c010acdc862ac66df;p=linux.git

crypto: algboss - remove redundant setting of len to zero

The variable len is set to zero, never read and then later updated
to p - name, so clearly the zero'ing of len is redundant and
can be removed.

Detected by clang scan-build:
" warning: Value stored to 'len' is never read"
