I tried doing the same thing at some point and never submitted.
For reference, here is my version. Yours looks better though,
so keep that.

    mfd: ab8500: remove duplicate table entries
    
    gcc -Wextra finds two duplicate initializations for ab8500_debug_ranges:
    
    drivers/mfd/ab8500-debugfs.c:466:11: error: initialized field overwritten 
[-Werror=override-init]
    drivers/mfd/ab8500-debugfs.c:466:11: note: (near initialization for 
'ab8500_debug_ranges[17]')
    drivers/mfd/ab8500-debugfs.c:470:11: error: initialized field overwritten 
[-Werror=override-init]
    drivers/mfd/ab8500-debugfs.c:470:11: note: (near initialization for 
'ab8500_debug_ranges[18]')
    
    In both cases, one initialization looks valid, the other one overrides
    it with an empty one. I'm removing the empty overrides now, assuming
    they were not intentional.
