Thanks for the driver! There are a lot of issues with the patch, though.

Most of the header files are not needed for this driver. The patch should
also be split into several parts (i.e. power_supply_sysfs.c changes should
be aside). In the patch there is a lot of dead (commented-out) code and
code that completely violates Linux coding standards.

I would say that for now, drivers/staging/ is more appropriate place for
the driver. Meanwhile, be sure to read Documentation/CodingStyle and
Documentation/SubmittingPatches. And a special url about #ifdefs in .c
files, typedefs, etc.:

Thanks,

Anton
