Subject[PATCH] IB/iser: remove uninitialized variable len
Date
From: Colin Ian King <colin.king@canonical.com>

The variable len is not being inintialized and the uninitialized
value is being returned. However, this return path is never reached
because the default case in the switch statement returns -ENOSYS.
Clean up the code by replacing the return -ENOSYS with a break
for the default case and returning -ENOSYS at the end of the
function. This allows len to be removed. Also remove redundant
break that follows a return statement.
