PCI: hv: Remove unused function hv_set_msi_entry_from_desc()

[PATCH -next] PCI: hv: Remove unused function hv_set_msi_entry_from_desc()

Posted by YueHaibing 4 years, 3 months ago

This patch fix the following build error:

drivers/pci/controller/pci-hyperv.c:769:13: error: ‘hv_set_msi_entry_from_desc’ defined but not used [-Werror=unused-function]
  769 | static void hv_set_msi_entry_from_desc(union hv_msi_entry *msi_entry,

On arm64 hv_set_msi_entry_from_desc() is not used anymore since
commit d06957d7a692 ("PCI: hv: Avoid the retarget interrupt hypercall in irq_unmask() on ARM64").
