Subject[BK PATCH] More i2c driver changes for 2.5.65
Hi,

Here are some more i2c driver changes for 2.5.65. These include changes
that now hook up the i2c devices to the driver core. This results in a
sysfs tree that looks like the following on one of my boxes:

/sys/bus/i2c/
|-- devices
| `-- i2c_dev_0 -> ../../../devices/pci0/00:1f.3/i2c-0/i2c_dev_0
`-- drivers
`-- LM75 sensor
`-- i2c_dev_0 -> ../../../../devices/pci0/00:1f.3/i2c-0/i2c_dev_0


Now the fun work of starting to rip out the i2c sysctl and proc code can
begin :)

These changesets also include the patch from Petr Vandrovec that fixes
an oops on booting with i2c built into the kernel, and some more minor
cleanups to some of the i2c core code.

I'll try to post a document later this weekend on lkml and
kernel-janitors-discuss that explains how the i2c drivers will need to
be converted, and how people can help out now that the infrastructure is
finished.

Please pull from: bk://kernel.bkbits.net/gregkh/linux/i2c-2.5

thanks,

greg k-h

i2c: ugh, clean up lindent mess in i2c-proc.c::i2c_detect()

Yes, this function now goes beyond 80 columns, but it's almost
readable, while the previous version was not.

Also removed some #ifdefs

i2c: actually register the i2c client device with the driver core.

We have to initialize the client structure with 0 to keep the
driver core from oopsing.

Now everything is hooked up enough to start removing the i2c sysctl
and proc crud.

[PATCH] i2c: remove the data field from struct i2c_client

It's no longer needed, as the struct device should be used instead.

Created i2c_get_clientdata() and i2c_set_clientdata() to access the data.

[PATCH] Fix kobject_get oopses triggered by i2c in 2.5.65-bk

i2c initialization must not use module_init now, when it was converted
to the kobject interface. There are dozens of users which need it working
much sooner. i2c is subsystem after all, isn't it?

Fixes kernel oopses in kobject_get during system init which were happening
to me.
