From there, create a Makefile with this line:

obj-m	+= w83627ehf.o

Then run:

make -C /usr/src/linux SUBDIRS=$PWD modules

(replace /usr/src/linux with the path to your real kernel source tree).

That should do it. If there are warnings or errors, you'll have to
figure out how to fix them (or ask us). Then modprobe the new driver and
see how it goes.

For the records, your chip has ID 0x8863, which matches the W83627EHF
datasheet (it says 0x886x), but oddly enough not the ID of the only
W83627EHF chip we saw so far (which had 0x8853). I have good hope that
both chips will be compatible as far as hardware monitoring is
concerned.

Oh, and remember that my w83627ehf driver is not finished, it only
implements half of the features the chip has, due to a lack of time and
hardware to test my work. Someone else is working on improving it. Or I
might do if someone considers a hardware donation.
