From 9821898bbfa5a21254baafe19b3cc97516fc6019 Mon Sep 17 00:00:00 2001

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.
