Hi all,
Following my first hwmon vs. i2c series of patches, which was mostly
aiming at moving non-i2c hardware monitoring drivers away from the
i2c-core, here comes a second series which goes one step further in the
direction of a clean separation of the hmwon-specific code from the i2c
subsystem. It is made up of 11 cumulative patches, which I will now
post.
This time, I am attempting to fix two different design errors that were
made in the early days of the sensors drivers and never fixed since: i2c
code being duplicated for the sensors drivers, and non i2c-related code
used by sensors drivers being attached to the i2c subsystem.
This results in a significant code shrink, both at source (-333 lines)
and binary (-2777 bytes) levels, and in large chunks of code being moved
from drivers/i2c to drivers/hwmon (and include/linux/i2c-*.h to
include/linux/hwmon-*.h.)
There are still a few cleanups I want to do on top of that, most notably
a rewrite of i2c_probe and a better handling of address lists, but this
series is certainly the most important (and intrusive) part of the
cleanup process.
I've tried to keep the documentation up-to-date with each patch, but it
seems that this documentation would still need a full review and update,
as it contains pretty inaccurate information at places. I'll tackle that
when I'm done with the code changes.
Thanks.
