This is done by not taking care of additional status bits. This is a
backport from Linux 2.6.

<klh@google.com> received Sept. '04.
No changes by me other than include file path fixups.
Compiles, but will not insmod without i2c-core changes
or stubs to add xxx_nolock() functions.
-----------------
Here you go. I apologize for the fact this code is not integrated
into the lm_sensors package structure and thus will require you to
make various little updates. But I really wanted to get this out
before I'm yanked away again, and am pretty sure you can do it much
faster than I can figure out what needs to be done!
BTW the kernel files are built against 2.4.x where x varies; 18 and 19
should work.
Feel free to clean up anything.

I'm sending you this little obvious patch which should enable i2c-piix
to work on IBM servers with ServerWorks chipsets. It still will treat
any IBM/Intel machine as a laptop and refuse to work, but it's better
than before.
git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@2570 7894878c-1315-0410-8ee3-d5d059ff63e0
patch from Ken Healy <k.healy@student.ucc.ie>
This patch experimentally enables SiS 655 support by the i2c-sis645 driver.
It simply modifies the driver to also accept the SiS 655 as a valid host
bridge.
Partially tested on a Gigabyte GA-SINXP1394 (SiS655/963), no problems so far.
Driver successfully enables the SMBus controller, i2cdetect finds the usual
devices, and i2cdump successfully reads the DIMM SPD eeprom's.
The patch is against the lm_sensors-2.8.5 release.

This patch fixes a "Trying to release non-existent resource" error that
occurs during rmmod when the device isn't actually present. It includes
some other cleanups too: error paths, whitespace, magic numbers, __devinit.

Subject: lm_sensors 2.8.2 / DESTDIR / root
The reason for this email is that I always try to avoid running
Makefiles as root, even during 'make install'. Therefore, I
always use the DESTDIR feature, when it's available. Until today,
I always built i2c and lm_sensors by doing
$ make
$ make -i install DESTDIR=/foo
$ cd /foo && su root && fix permissions/ownership && install
The -i flag to make install is a kludge to avoid having to be root
while installing to the DESTDIR, and it's only required because
the files are installed with "-o root -g root". Using the -i
flag is of course not a good idea, since more fatal errors can
easily fly by undetected.
Today, I upgraded to Linux 2.6.0, and tried a similar install
procedure for lm_sensors, except that the make target is now "user"
and the install target is "user_install". I now noticed that the
DESTDIR variable is not used everywhere in "user_install", so I
couldn't use the -i kludge anymore. Instead, I wrote a patch that
removes the "-o root -g root" arguments to install everywhere, and
I also tried to add DESTDIR to all files/directories installed.
(The patch only applies to lm_sensors, not i2c, since only
lm_sensors is required in Linux 2.6.0.)
There's really no reason to say -o root -g root anyway, since if you
do install directly with make install, you have to be logged in as
root, and then the files will get the right ownership by default.
Much of the point of installing to a temporary DESTDIR is that you
don't have to be root, and that you can prepare the installation
by hand. Fixing the ownership is trivial:
chown -R root.root $DESTDIR
