[PATCH] crypto: algboss: remove redundant setting of len to zero

From: Colin King
Date: Thu Sep 14 2017 - 14:02:31 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

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"
