    Subject[PATCH 4.14 74/80] ARC: hide unused function unw_hdr_alloc
    Date
    From: Arnd Bergmann <arnd@arndb.de>

    commit fd5de2721ea7d16e2b16c4049ac49f229551b290 upstream.

    As kernelci.org reports, this function is not used in
    vdk_hs38_defconfig:

    arch/arc/kernel/unwind.c:188:14: warning: 'unw_hdr_alloc' defined but not used [-Wunused-function]

    Fixes: bc79c9a72165 ("ARC: dw2 unwind: Reinstante unwinding out of modules")
