[2.6.0-test5-mm2] no /proc/bus/i2c but i2c-core module loaded + small oops

[Philippe Gramoullé]

 Hello,

Symptoms: modprobe i2c-core works fine but /proc/bus/i2c doesn't exist

Kernel  : Stock 2.6.0-test5-mm2
Distro  : Debian Sid + 2.8 lm-sensors user space utilities
Hardware: Dell WS 530MT SMP Xeon 1.5 Ghz, Intel Motherboard Chipset: 82801BA , ADM1023
	  00:1f.3 SMBus: Intel Corp. 82801BA/BAM SMBus (rev 04)

Also while rmmoding  i2c-dev module, i got the following message:


Device class 'i2c-0' does not have a release() function, it is broken and must be fixed.
Badness in class_dev_release at drivers/base/class.c:200

/proc/bus/i2c will never exist :)

lmsensors has not been ported to 2.6 yet, sorry.  Look in /sys/bus/i2c
for the devices and sensors.

Go check out sysfs.  i2c no longer uses proc. AFAIK system related proc 
entries will all move to sysfs.


No idea about the rmmod error.

Well, ok :) No need to say that i didn't follow closely recent evolutions 
regarding i2c. I just read but documentation but obviously not for the right kernel :)
