The following S390 build failed on stable-rc 5.15.y with gcc-12 and clang due
to following warnings and errors [1].

s390:
  build:
    * gcc-8-defconfig-fe40093d
    * gcc-12-defconfig
    * clang-18-defconfig


Reported-by: Linux Kernel Functional Testing <lkft@xxxxxxxxxx>

The bisect points to 5af75585e330 ("s390/pci: Rework MSI descriptor walk")
as the problematic commit [ Upstream commit
2ca5e908d0f4cde61d9d3595e8314adca5d914a1 ].
