Description
In the Linux kernel, the following vulnerability has been resolved: MIPS: Loongson64: DTS: Really fix PCIe port nodes for ls7a Fix the dtc warnings: arch/mips/boot/dts/loongson/ls7a-pch.dtsi:68.16-416.5: Warning (interrupt_provider): /bus@10000000/pci@1a000000: '#interrupt-cells' found, but node is not an interrupt provider arch/mips/boot/dts/loongson/ls7a-pch.dtsi:68.16-416.5: Warning (interrupt_provider): /bus@10000000/pci@1a000000: '#interrupt-cells' found, but node is not an interrupt provider arch/mips/boot/dts/loongson/loongson64g_4core_ls7a.dtb: Warning (interrupt_map): Failed prerequisite 'interrupt_provider' And a runtime warning introduced in commit 045b14ca5c36 ("of: WARN on deprecated #address-cells/#size-cells handling"): WARNING: CPU: 0 PID: 1 at drivers/of/base.c:106 of_bus_n_addr_cells+0x9c/0xe0 Missing '#address-cells' in /bus@10000000/pci@1a000000/pci_bridge@9,0 The fix is similar to commit d89a415ff8d5 ("MIPS: Loongson64: DTS: Fix PCIe port nodes for ls7a"), which has fixed the issue for ls2k (despite its subject mentions ls7a).
