Hi,
Here are some more i2c driver cleanups. These do the following items I
mentioned in my last set of patches:
- clean up #ifdef mess in i2c controllers
- fix the printk() calls to use proper levels
- add i2c controller driver core support
There is also a i2c spelling patch in here, and I've added the i2c-isa
driver, which almost isn't even a driver at all, based on the size of
it.
Even with adding a new driver, the sum of these patches is still a
smaller number of lines than we started with, which is always nice.
Please pull from: bk://kernel.bkbits.net/gregkh/linux/i2c-2.5
Things left to do after this:
- clean up i2c driver core support to work better.
- add i2c device core support.
- port remaining drivers from i2c cvs to kernel tree.
thanks,
greg k-h
