Hi Yani, Greg, all,

It seems that this patch never made it to Greg's tree. I have been
testing it for two weeks now, and no problem arose, so I'd like it to be
applied. Let's not lose the work that was done. Just like the adm1026
patch, the original it87 patch had some coding style error, which I
fixed. New patch attached. Please apply, thanks.
--------------------------------------------------------------
This patch modifies the it87 hardware monitoring driver to take benefit
of the new sysfs callback features introduced by Yani Ioannou, making
the code much clearer and the resulting driver significantly smaller.

From what I recall Greg was 'inspired' ;-) by your code to find a nice
way to aggregate the attributes into arrays, and hence it didn't get
applied right away. If we haven't got some nice solution for that at
the moment then this might as well be applied, although I do wonder if
creating an array and attribute group manually and registering all the
attributes as a group would be cleaner for now?

Ah, thanks for reminding me, I had somehow forgotten that episode.
However, I have plans to modify the it87 driver to only create the sysfs
files for channels which are really in use [1]. For example, I have an
IT8705F chip on my new motherboard, which has 3 unused voltage channels,
2 unused temperature channels and 1 unused fan channel. The driver will
still create the sysfs interface for them at the moment. I think this
isn't good. So it would probably be wiser to wait for me to implement
this, and then see whether using arrays of attributes still makes sense
(and how), rather than the other way around.
So I think we should apply the currently available patch for the it87
driver, and work on top of that later as time permits.
[1] Actually I have many more plans for the it87 driver than just this
one. It's amazing how easier it is to hack on any given driver once you
do have hardware to test your changes :)
Thanks,

It's just gaining that hardware that's the problem...now if only I
could afford a board with an IPMI 2.0 BMC with 60 sensors ;-)

Oops, that one slipped through, good catch. Applied now.
