    charger-manager: Simplify charger_get_property(), get rid of a warning
    
    This patch fixes the following warning and makes the code a little
    bit more simpler:
    
      CC      drivers/power/charger-manager.o
    charger-manager.c: In function 'charger_get_property':
    charger-manager.c:429:15: warning: 'i' may be used uninitialized in this function [-Wuninitialized]
