Subject: [PATCH 07/16] smsc: Replace spin_is_locked() with lockdep
Date: Tue, 2 Oct 2018 22:38:53 -0700 [thread overview]
Message-ID: <20181003053902.6910-8-ldr709@gmail.com> (raw)
In-Reply-To: <20181003053902.6910-1-ldr709@gmail.com>
lockdep_assert_held() is better suited to checking locking requirements,
since it won't get confused when someone else holds the lock. This is
also a step towards possibly removing spin_is_locked().
