Subject: NFSv4.1: Fix a kfree() of uninitialised pointers in
decode_cb_sequence_args
From: Trond Myklebust <[email protected]>
commit d8ba1f971497c19cf80da1ea5391a46a5f9fbd41 upstream.
If the call to decode_rc_list() fails due to a memory allocation error,
then we need to truncate the array size to ensure that we only call
kfree() on those pointer that were allocated.
