+Subject: aic7xxx leaves timer running on init failure
+References: bnc#469576
+
+aic79xx leaves timers inserted when ahd_init() (which inserts
+two timers at its very end) succeeds but ahd_pci_map_int()
+fails. In this case ahd->init_level gets incremented to 5 only
+when that function succeeds, but ahd_free() calls ahd_shutdown()
+only when ahd->init_level == 5, and ahd_shutdown() is where the
+timers get removed. Since the freeing of the IRQ is not controlled
+by ahd->init_level, we should increment init_level prior to
+calling ahd_pci_map_int().
