Add spin_lock_irqsave()/spin_unlock_irqrestore() around the
handle_dynamic_resolution_change() call in initialize_sequence() to fix
the missing lock protection.
initialize_sequence() calls handle_dynamic_resolution_change() without
holding inst->state_spinlock. However, handle_dynamic_resolution_change()
has lockdep_assert_held(&inst->state_spinlock) indicating that callers
must hold this lock.
Other callers of handle_dynamic_resolution_change() properly acquire the
spinlock:
- wave5_vpu_dec_finish_decode()
- wave5_vpu_dec_device_run()
