This is essentially a stripped down version of the W83627DHG. Noticeable
difference is that it is still powered with +5V, as older models, even
though the ADC resolution is 8 mV as newer models have.

The probe function has grown pretty large, I think it's time for some
cleanups, starting with these two simple ones:
* Move temp3/in6 check for the W83667HG later in the function, where
it is done for all other chip types.
* Move temperature register setting to a separate function, to avoid
code duplication.

Clean up the code to make it more readable:
* Remove reg_ and new_ prefixes from variable names, they made the

* Introduce struct device dev* = &client->dev in two functions, to
avoid repeating client->dev everywhere in these functions.

We can solve these easily by reading the register values first and
checking for errors later. These errors should be very rare, even in
the case of failed detection, so this change has no impact on
performance. And this makes checkpatch.pl happier.

While back-porting Johannes Weiner's patch "mm: memcg-aware global
reclaim" for an internal effort, we noticed a significant performance
regression during page-reclaim heavy workloads due to high contention of
the ss->id_lock. This lock protects idr map, and serializes calls to
idr_get_next() in css_get_next() (which is used during the memcg hierarchy
walk).
Since idr_get_next() is just doing a look up, we need only serialize it
with respect to idr_remove()/idr_get_new(). By making the ss->id_lock a
rwlock, contention is greatly reduced and performance improves.
Tested: cat a 256m file from a ramdisk in a 128m container 50 times on
each core (one file + container per core) in parallel on a NUMA machine.
Result is the time for the test to complete in 1 of the containers.
Both kernels included Johannes' memcg-aware global reclaim patches.

In testing aio on a fast storage device, I found that the context lock
takes up a fair amount of cpu time in the I/O submission path. The reason
is that we take it for every I/O submitted (see __aio_get_req). Since we
know how many I/Os are passed to io_submit, we can preallocate the kiocbs
in batches, reducing the number of times we take and release the lock.
In my testing, I was able to reduce the amount of time spent in
_raw_spin_lock_irq by .56% (average of 3 runs). The command I used to
test this was:
aio-stress -O -o 2 -o 3 -r 8 -d 128 -b 32 -i 32 -s 16384 <dev>
I also tested the patch with various numbers of events passed to
io_submit, and I ran the xfstests aio group of tests to ensure I didn't
break anything.
