i2c: Migration aids for i2c_adapter.dev removal
Flag i2c_adapter.dev for removal after userspace tools get upgraded, and include a near-term code migration aid to facilitate this: - The class device gets the name attribute it should have had. This was previously (wrongly) associated with the i2c_adapter.dev node. Sysfs based tools and libraries can start converting right away. - Issue a warning for legacy adapter drivers that don't provide any physical device node; so systems with those drivers will know to fix this problem earlier. This is one of a series of patches to help the I2C stack become a better citizen of the Linux Driver Model world.

+What: i2c_adapter.dev
+ i2c_adapter.list
+When: July 2007
+Why: Superfluous, given i2c_adapter.class_dev:
+ * The "dev" was a stand-in for the physical device node that legacy
+ drivers would not have; but now it's almost always present. Any
+ remaining legacy drivers must upgrade (they now trigger warnings).
+ * The "list" duplicates class device children.
+ The delay in removing this is so upgraded lm_sensors and libsensors
+ can get deployed. (Removal causes minor changes in the sysfs layout,
+ notably the location of the adapter type name and parenting the i2c
+ client hardware directly from their controller.)
