From: Bryan Schumaker <bjschuma@xxxxxxxxxx>
When compiling, I was getting this warning:
fs/nfs/nfs4xdr.c: In function âdecode_secinfoâ:
fs/nfs/nfs4xdr.c:4839:6: warning: variable âstatusâ set but not used
[-Wunused-but-set-variable]
We were unconditionally returning 0 as long as there wasn't an error
coming out of xdr_inline_decode(). We probably want to check the error
status coming out of decode_op_hdr() and decode_secinfo_gss(), rather
than assuming that everything is OK all the time.
