+Subject: [PATCH 178/226] staging: fsl-mc: bus: Drop warning
+
+When updating the irq_chip and msi_domain_ops, the code checkes for
+already present functions.
+When more then one ITS controller are present in the system,
+irq_chip and msi_domain_ops got already set and a warning is invoked.
+
+This patch deletes the warning, as the funtions are just already set to
+the needed callbacks.
