With CONFIG_OF=n I got this:

  CC      drivers/power/sbs-battery.o
  drivers/power/sbs-battery.c: In function ‘sbs_probe’:
  drivers/power/sbs-battery.c:707:20: error: ‘struct power_supply’ has no
  member named ‘of_node’
  make[1]: *** [drivers/power/sbs-battery.o] Error 1

I fixed this by the patch below and applied your 1-3 series.

Thanks!

Anton

    power_supply: Move of_node out of the #ifdef CONFIG_OF
    
    Similar to linux/device.h, move of_node struct member out of the #ifdef
    CONFIG_OF so that the drivers won't have to mess with #ifdefs in .c files.
