Thanks for the patch!
Applied to battery-2.6.git, with some changes.

Should be max17042_id, otherwise build breaks when enabled as a module:
drivers/power/max17042_battery.c:214: error: â__mod_i2c_device_tableâ aliased to undefined symbol âmax17040_idâ
Also a few small cosmetic changes were made. Here is the whole
