    scripts/kernel-doc: Don't fail with status != 0 if error encountered with -none · 9537ff76

    My bisect scripts starting running into build failures when trying to
    compile 4.15-rc1 with the builds failing with things like:
    
    drivers/net/wireless/broadcom/brcm80211/brcmfmac/sdio.c:2078: error: Cannot parse struct or union!
    
    The line in question is actually just a #define, but after some digging
    it turns out that my scripts pass W=1 and since commit 3a025e1d
    ("Add optional check for bad kernel-doc comments") that results in
    kernel-doc running on each source file. The file in question has a
    badly formatted comment immediately before the #define:
    
    /**
     * struct brcmf_skbuff_cb reserves first two bytes in sk_buff::cb for
     * bus layer usage.
     */
    
    which causes the regex in dump_struct to fail (lack of braces following
    struct declaration) and kernel-doc returns 1, which causes the build
    to fail.
    
    Fix the issue by always returning 0 from kernel-doc when invoked ...
