Subject[PATCH 3.16 47/63] uas: replace WARN_ON_ONCE() with lockdep_assert_held()
3.16.58-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Sanjeev Sharma <sanjeev_sharma@mentor.com>

commit ab945eff8396bc3329cc97274320e8d2c6585077 upstream.

on some architecture spin_is_locked() always return false in
uniprocessor configuration and therefore it would be advise
to replace with lockdep_assert_held().
