Hi,
  Shouldn't "walk" be memset ?

FILE:            crypto/cbc.c
FUNCTION:  crypto_cbc_encrypt

"walk" is local variable and its uninitialized in
"crypto_cbc_encrypt". The same is passed to
"blkcipher_walk_virt" which does below

walk->flags &= ~BLKCIPHER_WALK_PHYS;

So neither 'walk' nor 'walk->flags' is memset or init to a proper value.

Thanks,
Pavi
