3.5.7.3 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Xi Wang <[email protected]> commit e25fbe380c4e3c09afa98bcdcd9d3921443adab8 upstream. The following null pointer check is broken. *option = match_strdup(args); return !option; The pointer `option' must be non-null, and thus `!option' is always false. Use `!*option' instead. The bug was introduced in commit c5cb09b6f8 ("Cleanup: Factor out some cut-and-paste code.").
