    sh: Fix set but not used warnings with !CONFIG_MMU
    
    Building fbdev drivers for sh with W=1 produces the following warning:
    
        tmiofb.c: In function ‘tmiofb_remove’:
        tmiofb.c:805:21: warning: variable ‘par’ set but not used
    
    This is with allmodconfig and ARCH=sh
    
    This boiled down to iounmap() defined as empty for !CONFIG_MMU.
    Fix this by by adding "(void)addr;" to tell the compiler the
    argument to iounmap() should be considered used.
    
    v4:
      - Fix build error of ethernet driver (kernel test robot)
        Added missing () around macro parameter

Thanks for thee quick report - it was easy to reproduce.
I hope this is enough for the robot to pick up the updated patch.
