Never mind. I figured it out. The commit that changed the behavior is : commit de0a41484c47d783dd4d442914815076aa2caac2 Author: Paul Gortmaker <[email protected]> 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 ani On Tue, May 24, 2016 at 1:10 PM, Ani Sinha <[email protected]> wrote: > Hi guys : > > I am facing this interesting issue and I can't quite figure out what > the root cause is.
