CVE-2024-56785

Estado: ModificadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

MIPS: Loongson64: DTS: Really fix PCIe port nodes for ls7a

Fix the dtc warnings:

And a runtime warning introduced in commit 045b14ca5c36 ("of: WARN on deprecated #address-cells/#size-cells handling"):

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).
