PATCH 1/1 i2c driver changes for 2.5.68

Hi,

Here are some i2c driver changes for 2.5.68. These include a lot of cleanup patches, removing dead or duplicated code. With these patches, we are almost able to remove i2c-sensor.h and i2c-sensor.c, but not quite there. Also a new i2c chip driver has been added.

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

thanks,

greg k-h

[PATCH] i2c: remove dead code from adm1021
