Using s8 instead of u8 to store temperature register values saves a
few instructions on sysfs file read. The very same was done for
several other drivers a while ago (lm63, lm83, lm90...)

Convert the w83l785ts driver to use dynamic sysfs callbacks. This is a
small driver so the benefit is thin, but still worth it.

Clean up name string usage in 12 i2c bus drivers:
* Use the i2c_adapter name for requesting the I/O region rather than
redefining a new string.
* Do not initialize the i2c_adapter name to "unset".
This should save a few data bytes here and there.

Do not enable the VIA VT82C686A/B integrated sensors by default, as
disabled sensors usually means that this feature is not used so the
values won't make any sense. This has been confusing many users in the
past:

It is still possible to forcibly enable the sensors by using the
force_addr module parameter.

hwmon: adm9240 update 2/2: convert to use dynamic sysfs accessors
This patch converts adm9240 to use Yani Ioannou's dynamic sysfs callbacks,
reducing driver memory footprint from 16312 to 14104 bytes on 2.6.14-rc1,
removing the old driver macro mess.
Run tested on Intel SE440BX-2 mobo.

In PM v1, all devices were called at SUSPEND_DISABLE level. Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level. However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.
Since this is obsolete infrastructure which is no longer necessary,
we can remove it. Here's an (untested) patch to do exactly that.

There are a number of sparse warnings from the latest sparse
snapshot being generated from the drivers/base build. The
main culprits are due to the initialisation functions not
being declared in a header file.
Also, the firmware.c file should include <linux/device.h>
to get the prototype of firmware_register() and
firmware_unregister().
This patch moves the init function declerations from the
init.c file to the base.h, and ensures it is included in
all the relevant c sources. It also adds <linux/device.h>
to the included headers for firmware.c.
The patch does not solve all the sparse errors generated,
but reduces the count significantly.

This patch allows struct class_device to be nested, so that another
struct class_device can be the parent of a new one, instead of only
having the struct class be the parent. This will allow us to
(hopefully) fix up the input and video class subsystem mess.
But please people, don't go crazy and start making huge trees of class
devices, you should only need 2 levels deep to get everything to work
(remember to use a class_interface to get notification of a new class
device being added to the system.)
Oh, this also allows us to have the possibility of potentially, someday,
moving /sys/block into /sys/class. The main hindrance is that pesky
/dev numberspace issue...
