stable inclusion from linux-4.19.196 commit 8fa2bb8837ea92f725e63ec38935195bc0266668
--------------------------------
[ Upstream commit 515da6f4295c2c42b8c54572cce3d2dd1167c41e ]
On realtime kernels, spin_lock_irq*(spinlock_t) do not disable the interrupts, a call to irqs_disabled() will return false thus firing a warning in __transport_wait_for_tasks().
Remove the warning and also replace assert_spin_locked() with lockdep_assert_held()
