Hi all,

After merging the irqchip tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/pci/controller/pci-hyperv.c: In function 'hv_compose_msi_req_v2':
drivers/pci/controller/pci-hyperv.c:1654:42: error: passing argument 1 of 'hv_compose_msi_req_get_cpu' discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]
 1654 |         cpu = hv_compose_msi_req_get_cpu(affinity);
      |                                          ^~~~~~~~

cc1: all warnings being treated as errors

Caused by commit

  4d0b8298818b ("genirq: Return a const cpumask from irq_data_get_affinity_mask")

I have used the irqchip tree from next-20220707 for today.
