Koen Vandeputte 3b53d6fdbc ar71xx: fix pci irq init on kernel 4.14 ... The IRQ init structs are marked as __initconst which means this memory can be free after init. On this platform, the PCI IRQ init happens very late _after_ the kernel already freed the memory allocated for these structs. During IRQ allocation, the allocation function is passed with invalid data at this point leading to following error: [ 0.000000] SoC: Qualcomm Atheros QCA9533 ver 2 rev 0 [ 2.382828] Freeing unused kernel memory: 264K [ 34.414816] pci 0000:00:00.0: no irq found for pin 1 and [ 0.000000] SoC: Qualcomm Atheros QCA956X ver 1 rev 0 [ 2.125401] Freeing unused kernel memory: 284K [ 9.526479] pci 0000:00:00.0: no irq found for pin 1 After this patch: [ 14.960814] pci 0000:00:00.0: using irq 40 for pin 1 Commit 318e19ba67 ("ar71xx: add v4.14 support") fixed this for the default targets already present in the source by default but forgot to remove the __initconst attribute for targets QCA953x and QCA956x which are only added later through platform patches.
