Re: hwmon.c as a kernel module in 3.18

Never mind. I figured it out. The commit that changed the behavior is :

commit de0a41484c47d783dd4d442914815076aa2caac2
Author: Paul Gortmaker <paul.gortmaker@windriver.com>
Date:   Mon Oct 1 11:43:49 2012 -0400
    tg3: unconditionally select HWMON support when tg3 is enabled.

So I had exactly this combination : CONFIG_TG3 was 'y' whereas
CONFIG_HWMON was 'm'.

I have fixed it now.

thanks
