[PATCH 01/10] MSI: Rename msi_chip to msi_controller for better readability
From: Yijing Wang
Date: Mon Oct 27 2014 - 03:08:17 EST
"msi_chip" name has bad readability, it easily confuses
people that some sort of semiconductor integrated circuit
involved. Rename it to "msi_controller", it's more
descriptive, and arm also use "msi-controller" property
to represent MSI interrupt controller in dts file.
Should no functional change.
