            Bug ID: 16093
           Summary: kmod and gcc-14 build error
           Product: buildroot
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
          Assignee: unassigned@buildroot.uclibc.org
          Reporter: lancethepants@gmail.com
                CC: buildroot@uclibc.org
  Target Milestone: ---

Trying out 2024.05-rc1 ran into this issue when using gcc-14. Minimum defconfig
below. I saw a patch in patchwork, but it wasn't gcc-14 related and didn't work
here when applying it.
