Subject: lockdep, bug: Exclude TAINT_OOT_MODULE from disabling lock debugging

From: Ben Hutchings <ben@decadent.org.uk>

commit 9ec84acee1e221d99dc33237bff5e82839d10cc0 upstream.

We do want to allow lock debugging for GPL-compatible modules
that are not (yet) built in-tree. This was disabled as a
side-effect of commit 2449b8ba0745327c5fa49a8d9acffe03b2eded69
('module,bug: Add TAINT_OOT_MODULE flag for modules not built
in-tree'). Lock debug warnings now include taint flags, so
kernel developers should still be able to deflect warnings
caused by out-of-tree modules.

The TAINT_PROPRIETARY_MODULE flag for non-GPL-compatible modules
will still disable lock debugging.
