[PATCH] PCI/ACPI: make array pcie_to_hpx3_type static const, makes object smaller

From: Colin King
Date: Mon Feb 10 2020 - 03:53:02 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Don't populate the array pcie_to_hpx3_type on the stack but instead
make it static const. Makes the object code smaller by 6 bytes:

Before:
text data bss dec hex filename
19247 3048 64 22359 5757 drivers/pci/pci-acpi.o

After:
text data bss dec hex filename
19177 3112 64 22353 5751 drivers/pci/pci-acpi.o

(gcc version 9.2.1, amd64)
