    How about ERR_CAST() instead? Or maybe CAST_ERR()?

    struct dentry *blah(...)
    {
    struct inode *inode;

    inode = thing(...);
    if (IS_ERR(inode))
    return ERR_CAST(inode);
    }

    Where ERR_CAST is defined as:

    static inline void *ERR_CAST(const void *error)
    {
    return (void *) x;
    }
