[26/74] fix affs parse_options()

From: Greg KH
Date: Thu Feb 04 2010 - 12:33:38 EST


2.6.32-stable review patch. If anyone has any objections, please let us know.

------------------

From: Al Viro <viro@xxxxxxxxxxxxxxxxxx>

commit 217686e98321a4ff4c1a6cc535e511e37c5d2dbf upstream.

Error handling in that sucker got broken back in 2003. If function
returns 0 on failure, it's not nice to add return -EINVAL into it.
Adding return 1 on other failure exits is also not a good thing (and
yes, original success exits with 1 and some of failure exits with 0
are still there; so's the original logics in callers).
