    linuxkpi: Add `show_fdinfo()` to `struct file_operations`
    
    We never call this field but it allows to compile drivers without
    modifications.
    
    This is used by the DRM drivers for some time, but another change part
    of the update to Linux 6.8 led to compile them with `CONFIG_PROC_FS`.
    This connected code that uses this struct field.
