    sysctl: treewide: drop unused argument ctl_table_root::set_ownership(table)
    
    [ Upstream commit 520713a93d550406dae14d49cdb8778d70cecdfd ]
    
    Remove the 'table' argument from set_ownership as it is never used. This
    change is a step towards putting "struct ctl_table" into .rodata and
    eventually having sysctl core only use "const struct ctl_table".
    
    The patch was created with the following coccinelle script:
    
      @@
      identifier func, head, table, uid, gid;
      @@
    
      void func(
        struct ctl_table_header *head,
      - struct ctl_table *table,
        kuid_t *uid, kgid_t *gid)
      { ... }
    
    No additional occurrences of 'set_ownership' were found after doing a
    tree-wide search.
