Hello,

That error is very wierd. It implies that CONFIG_EXTCON is "not
defined" in extcon.h and CONFIG_EXTCON is "defined" in Makefile so
that extcon_class.c is compiled.

However, the patchset v8 (some bugfixes over patchset v7) that is
tested on the base of Linux 3.4-rc3 w/ and w/o CONFIG_EXTCON and has
been used with MAX77693-MUIC devices is on the way.

Thanks.


Cheers!
MyungJoo.
