[i2c] [lm-sensors] i2c-i801 Interrupt Support

[Ivo Manca]

(Moving to I2C Mailinglist)

Hey Jean,

Actually, that problem was discussed in a different thread than the one 
I refered to. It can be found at: 
http://thread.gmane.org/gmane.linux.drivers.sensors/7987/focus=8021

So my question basically is: is the interrupt support removed from the 
i801 busriver because it was impossible to get it working right, is it 
removed because of, for instance, lack of time, or is it just never merged?
Since Mark M. Hoffman developed this driver with included interrupt 
support, and you seem to have tested it back them, I'm wondering if 
there is some more background information available about this, before 
we're starting working on something which might not be very possible.
