"msi_chip" isn't very descriptive, so rename it to "msi_controller". That tells a little more about what it does and is already used in device tree bindings. No functional change. [bhelgaas: changelog, change *only* the struct name so it's reviewable] Suggested-by: Bjorn Helgaas <bhelgaas@google.com> Signed-off-by: Yijing Wang <wangyijing@huawei.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
